New International Version
The Birth of Isaac
1Now the Lord was gracious to Sarah as he had said, and the Lord did for Sarah what he had promised. 2Sarah became pregnant and bore a son to Abraham in his old age, at the very time God had promised him. 3Abraham gave the name Isaaca to the son Sarah bore him. 4When his son Isaac was eight days old, Abraham circumcised him, as God commanded him. 5Abraham was a hundred years old when his son Isaac was born to him.
6Sarah said, “God has brought me laughter, and everyone who hears about this will laugh with me.” 7And she added, “Who would have said to Abraham that Sarah would nurse children? Yet I have borne him a son in his old age.”
Hagar and Ishmael Sent Away
8The child grew and was weaned, and on the day Isaac was weaned Abraham held a great feast. 9But Sarah saw that the son whom Hagar the Egyptian had borne to Abraham was mocking, 10and she said to Abraham, “Get rid of that slave woman and her son, for that woman’s son will never share in the inheritance with my son Isaac.”
11The matter distressed Abraham greatly because it concerned his son. 12But God said to him, “Do not be so distressed about the boy and your slave woman. Listen to whatever Sarah tells you, because it is through Isaac that your offspringb will be reckoned. 13I will make the son of the slave into a nation also, because he is your offspring.”
14Early the next morning Abraham took some food and a skin of water and gave them to Hagar. He set them on her shoulders and then sent her off with the boy. She went on her way and wandered in the Desert of Beersheba.
15When the water in the skin was gone, she put the boy under one of the bushes. 16Then she went off and sat down about a bowshot away, for she thought, “I cannot watch the boy die.” And as she sat there, shec began to sob.
17God heard the boy crying, and the angel of God called to Hagar from heaven and said to her, “What is the matter, Hagar? Do not be afraid; God has heard the boy crying as he lies there. 18Lift the boy up and take him by the hand, for I will make him into a great nation.”
19Then God opened her eyes and she saw a well of water. So she went and filled the skin with water and gave the boy a drink.
The Treaty at Beersheba
22At that time Abimelek and Phicol the commander of his forces said to Abraham, “God is with you in everything you do. 23Now swear to me here before God that you will not deal falsely with me or my children or my descendants. Show to me and the country where you now reside as a foreigner the same kindness I have shown to you.”
24Abraham said, “I swear it.”
25Then Abraham complained to Abimelek about a well of water that Abimelek’s servants had seized. 26But Abimelek said, “I don’t know who has done this. You did not tell me, and I heard about it only today.”
27So Abraham brought sheep and cattle and gave them to Abimelek, and the two men made a treaty. 28Abraham set apart seven ewe lambs from the flock, 29and Abimelek asked Abraham, “What is the meaning of these seven ewe lambs you have set apart by themselves?”
30He replied, “Accept these seven lambs from my hand as a witness that I dug this well.”
32After the treaty had been made at Beersheba, Abimelek and Phicol the commander of his forces returned to the land of the Philistines. 33Abraham planted a tamarisk tree in Beersheba, and there he called on the name of the Lord, the Eternal God. 34And Abraham stayed in the land of the Philistines for a long time.
