Genesis 21

And Yahweh visited Sarah as he had said. And Yahweh did to Sarah as he had promised. And she conceived, and Sarah bore to Abraham a son in his old age at the appointed time that God had told him. And Abraham called the name of his son who was born to him, whom Sarah bore to him, Isaac. And Abraham circumcised Isaac his son when he was eight days old, as God had commanded him. And Abraham was one hundred years old when Isaac his son was born to him. And Sarah said, “God has made laughter for me; all who hear will laugh for me.” And she said, “Who would announce to Abraham that Sarah would nurse children? Yet I have borne a son to Abraham in his old age.” And the child grew and was weaned. And Abraham made a great feast on the day Isaac was weaned. And Sarah saw the son of Hagar the Egyptian, whom she had borne Abraham, mocking. Then she said to Abraham, “Drive out this slave woman and her son, for the son of this slave woman will not be heir with my son, with Isaac.” And the matter displeased Abraham very much on account of his son. Then God said to Abraham, “Do not be displeased on account of the boy and on account of the slave woman. Listen to everything that Sarah said to you, for through Isaac your offspring will be named. And I will also make the son of the slave woman into a nation, for he is your offspring.” Then Abraham rose up early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder. And he sent her away with the child, and she went, wandering about in the wilderness, in Beersheba. And when the water was finished from the skin, she put the child under one of the bushes. And she went and she sat opposite him, at a distance, a bowshot away, for she said, “Let me not see the child’s death.” So she sat away from him and lifted up her voice and wept. And God heard the cry of the boy and the angel of God called to Hagar from the heavens and said to her, “What is the matter Hagar? Do not be afraid, for God has heard the cry of the boy from where he is. Get up, take up the boy and take him with your hand, for I will make him a great nation.” And God opened her eyes, and she saw a well of water. And she went and filled the skin with water and gave a drink to the boy. And God was with the boy, and he grew and lived in the wilderness. And he became an expert with a bow. And he lived in the wilderness of Paran. And his mother took a wife for him from the land of Egypt. And it happened that at that time, Abimelech and Phicol, the commander of his army, said to Abraham, “God is with you, in all that you do. So now, swear to me here by God that you will not deal with me falsely, or with my descendants, or my posterity. According to the kindness that I have done to you, you shall pledge to do with me and with the land where you have dwelled as an alien.” And Abraham said, “I swear.” Then Abraham complained to Abimelech on account of the well of water that servants of Abimelech had seized. And Abimelech said, “I do not know who did this thing, neither did you tell me, nor have I heard of it except for today.” And Abraham took sheep and cattle and gave them to Abimelech. And the two of them made a covenant. Then Abraham set off seven ewe-lambs of the flock by themselves. And Abimelech said to Abraham, “What is the meaning of these seven ewe-lambs that you have set off by themselves?” And he said, “You shall take the seven ewe-lambs from my hand as proof on my behalf that I dug this well.” Therefore that place is called Beersheba, because there the two of them swore an oath. And they made a covenant at Beersheba. And Abimelech, and Phicol his army commander stood and returned to the land of the Philistines. And he planted a tamarisk tree in Beersheba, and there he called on the name of Yahweh, the everlasting God. And Abraham dwelled as an alien in the land of the Philistines many days.

Genesis 21

This is a chapter of fulfillment and transition. After decades of waiting, Sarah gives birth to Isaac, the promised child. His name means “laughter,” echoing both disbelief and joy. But the joy comes with hard choices—particularly when tensions rise between Sarah and Hagar, leading to the painful sending away of Hagar and Ishmael. Yet even in that sorrow, God shows up. This chapter reminds us that God’s promises are trustworthy, His timing is perfect, and His care extends to all who call on Him.

Section 1: Genesis 21:1-7 The Promise Fulfilled

1 The LORD visited Sarah as he had said, and the LORD did to Sarah as he had promised. 2 And Sarah conceived and bore Abraham a son in his old age at the time of which God had spoken to him. 3 Abraham called the name of his son who was born to him, whom Sarah bore him, Isaac. 4 And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. 5 Abraham was a hundred years old when his son Isaac was born to him. 6 And Sarah said, “God has made laughter for me; everyone who hears will laugh over me.” 7 And she said, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”

Discussion Prompts:

  • Who is the main character in this passage? Why do you say that?
  • How does this moment of laughter connect back to earlier chapters?
  • How many times has God spoken to Sarah before this?
  • What does Abraham do here to keep the original covenant?
    • If Isaac is the child of promise, representing the new covenant, why do you think Abraham did this?
    • How might this help us understand the relationship between the Old and New Testaments? What does it teach us about obedience and faith today?
  • Rhetorical: What in your life today seems too big? God can handle it.

Section 2: Genesis 21:8-14 Conflict in the Camp

8 And the child grew and was weaned. And Abraham made a great feast on the day that Isaac was weaned. 9 But Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, laughing. 10 So she said to Abraham, “Cast out this slave woman with her son, for the son of this slave woman shall not be heir with my son Isaac.” 11 And the thing was very displeasing to Abraham on account of his son. 12 But God said to Abraham, “Be not displeased because of the boy and because of your slave woman. Whatever Sarah says to you, do as she tells you, for through Isaac shall your offspring be named. 13 And I will make a nation of the son of the slave woman also, because he is your offspring.” 14 So Abraham rose early in the morning and took bread and a skin of water and gave it to Hagar, putting it on her shoulder, along with the child, and sent her away. And she departed and wandered in the wilderness of Beersheba.

Discussion Prompts:

  • Tell us what is happening in this section.
  • Why do you think Sarah reacted so strongly toward Hagar and Ishmael?
  • What do you make of Abraham’s distress and God’s reassurance?
  • How do we handle situations where obedience to God involves pain or letting go?

Section 3: Genesis 21:15-21 God Hears the Outcast

15 When the water in the skin was gone, she put the child under one of the bushes. 16 Then she went and sat down opposite him a good way off, about the distance of a bowshot, for she said, “Let me not look on the death of the child.” And as she sat opposite him, she lifted up her voice and wept. 17 And God heard the voice of the boy, and the angel of God called to Hagar from heaven and said to her, “What troubles you, Hagar? Fear not, for God has heard the voice of the boy where he is. 18 Up! Lift up the boy, and hold him fast with your hand, for I will make him into a great nation.” 19 Then God opened her eyes, and she saw a well of water. And she went and filled the skin with water and gave the boy a drink. 20 And God was with the boy, and he grew up. He lived in the wilderness and became an expert with the bow. 21 He lived in the wilderness of Paran, and his mother took a wife for him from the land of Egypt.

Discussion Prompts:

  • What stands out to you about God’s response to Hagar and Ishmael in the wilderness?
  • How does this passage reveal God’s character?
  • Who in your life might feel forgotten or cast out—and how might you reflect God’s care toward them?

Section 4: Genesis 21: 22-34 Peace and Provision

22 At that time Abimelech and Phicol the commander of his army said to Abraham, “God is with you in all that you do. 23 Now therefore swear to me here by God that you will not deal falsely with me or with my descendants or with my posterity, but as I have dealt kindly with you, so you will deal with me and with the land where you have sojourned.” 24 And Abraham said, “I will swear.” 25 When Abraham reproved Abimelech about a well of water that Abimelech’s servants had seized, 26 Abimelech said, “I do not know who has done this thing; you did not tell me, and I have not heard of it until today.” 27 So Abraham took sheep and oxen and gave them to Abimelech, and the two men made a covenant. 28 Abraham set seven ewe lambs of the flock apart. 29 And Abimelech said to Abraham, “What is the meaning of these seven ewe lambs that you have set apart?” 30 He said, “These seven ewe lambs you will take from my hand, that this may be a witness for me that I dug this well.” 31 Therefore that place was called Beersheba, because there both of them swore an oath. 32 So they made a covenant at Beersheba. Then Abimelech and Phicol the commander of his army rose up and returned to the land of the Philistines. 33 Abraham planted a tamarisk tree in Beersheba and called there on the name of the LORD, the Everlasting God. 34 And Abraham sojourned many days in the land of the Philistines.

Discussion Prompts:

  • Why do you think Abimelech approached Abraham for a treaty?
  • How does Abraham’s response reflect growth in his faith journey?
  • What does this tell us about living at peace with others as we walk with God?

Wrap it Up

God wants a people set apart for righteousness - a holy people. This brings honor to Him. He invites us to be set apart and to join Him on mission.

Hear and respond to God, the Lord of the covenant.

  • What is your heart’s desire?

I hope that your answer to that is some form of wanting to know God more, to be more like Jesus.

And that leads us into our reflection on being clean vessels to be used by God.
