The Birth of Isaac

21

The L ord dealt with Sarah as he had said, and the L ord did for Sarah as he had promised. 2Sarah conceived and bore Abraham a son in his old age, at the time of which God had spoken to him. 3Abraham gave the name Isaac to his son whom Sarah bore him. 4And Abraham circumcised his son Isaac when he was eight days old, as God had commanded him. 5Abraham was a hundred years old when his son Isaac was born to him. 6Now Sarah said, “God has brought laughter for me; everyone who hears will laugh with me.” 7And she said, “Who would ever 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

8 The child grew, and was weaned; and Abraham made a great feast on the day that Isaac was weaned. 9But Sarah saw the son of Hagar the Egyptian, whom she had borne to Abraham, playing with her son Isaac. 10So she said to Abraham, “Cast out this slave woman with her son; for the son of this slave woman shall not inherit along with my son Isaac.” 11The matter was very distressing to Abraham on account of his son. 12But God said to Abraham, “Do not be distressed because of the boy and because of your slave woman; whatever Sarah says to you, do as she tells you, for it is through Isaac that offspring shall be named for you. 13As for the son of the slave woman, I will make a nation of him also, because he is your offspring.” 14So 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 about in the wilderness of Beer-sheba.

15 When the water in the skin was gone, she cast the child under one of the bushes. 16Then she went and sat down opposite him a good way off, about the distance of a bowshot; for she said, “Do not let me look on the death of the child.” And as she sat opposite him, she lifted up her voice and wept. 17And 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? Do not be afraid; for God has heard the voice of the boy where he is. 18Come, lift up the boy and hold him fast with your hand, for I will make a great nation of him.” 19Then God opened her eyes and she saw a well of water. She went, and filled the skin with water, and gave the boy a drink.

20 God was with the boy, and he grew up; he lived in the wilderness, and became an expert with the bow. 21He lived in the wilderness of Paran; and his mother got a wife for him from the land of Egypt.

Abraham and Abimelech Make a Covenant

22 At that time Abimelech, with Phicol the commander of his army, said to Abraham, “God is with you in all that you do; 23now therefore swear to me here by God that you will not deal falsely with me or with my offspring or with my posterity, but as I have dealt loyally with you, you will deal with me and with the land where you have resided as an alien.” 24And Abraham said, “I swear it.”

25 When Abraham complained to Abimelech about a well of water that Abimelech’s servants had seized, 26Abimelech said, “I do not know who has done this; you did not tell me, and I have not heard of it until today.” 27So Abraham took sheep and oxen and gave them to Abimelech, and the two men made a covenant. 28Abraham set apart seven ewe lambs of the flock. 29And Abimelech said to Abraham, “What is the meaning of these seven ewe lambs that you have set apart?” 30He said, “These seven ewe lambs you shall accept from my hand, in order that you may be a witness for me that I dug this well.” 31Therefore that place was called Beer-sheba; because there both of them swore an oath. 32When they had made a covenant at Beer-sheba, Abimelech, with Phicol the commander of his army, left and returned to the land of the Philistines. 33Abraham planted a tamarisk tree in Beer-sheba, and called there on the name of the L ord, the Everlasting God. 34And Abraham resided as an alien many days in the land of the Philistines.


1. And the Lord visited Sarah. In this chapters not only is the nativity of Isaac related, but because, in his very birth, God has set before us a lively picture of his Church, Moses also gives a particular account of this matter. And first, he says that God visited Sarah, as he had promised. Because all offspring, flows from the kindness of God, as it is in the psalm,

‘The fruit of the womb is the gift of God;’ (Psalm 127:3;)

therefore the Lord is said, not without reason, to visit those, to whom he gives children. For although the foetus seems to be produced naturally, each from its own kind; there is yet no fecundity in animals, except so far as the Lord puts forth his own power, to fulfill what he has said, Increase and multiply. But in the propagation of the human race, his special benediction is conspicuous; and, therefore, the birth of every child is rightly deemed the effect of divine visitation. But Moses, in this place, looks higher, forasmuch as Isaac was born out of the accustomed course of nature.433433     Calvin here adds, “Nam communis gignendi ratio, et vis illa quam Dominus hominibus indidit, in Abraham et ejus uxore cessaverat.” Therefore Moses here commends that secret and unwonted power of God, which is superior to the law of nature; and not improperly, since it is of great consequence for us to know that the gratuitous kindness of God reigned, as well in the origin, as in the progress of the Church; and that the sons of God were not otherwise born, than from his mere mercy. And this is the reason why he did not make Abraham a father, till his body was nearly withered. It is also to be noticed, that Moses declares the visitation which he mentions, to be founded upon promise; ‘Jehovah visited Sarah, as he had promised.’ In these words he annexes the effect to its cause, in order that the special grace of God, of which an example is given in the birth of Isaac, might be the more perceptible. If he had barely said, that the Lord had respect unto Sarah, when she brought forth a son; some other cause might have been sought for. None, however, can doubt, that the promise, by which Isaac had been granted to his father Abraham, was gratuitous; since the child was the fruit of that adoption, which can be ascribed to nothing but the mere grace of God. Therefore, whoever wishes rightly and prudently to reflect upon the work of God, in the birth of Isaac, must necessarily begin with the promise. There is also great emphasis in the repetition, “The Lord did unto Sarah as he had spoken.” For he thus retains his readers, as by laying his hand upon them, that they may pause in the consideration of so great a miracle. Meanwhile, Moses commends the faithfulness of God; as if he had said he never feeds men with empty promises, nor is he less true in granting what he has promised, than he is liberal, and willing, in making the promise.

2. She bare Abraham a son. This is said according to the accustomed manner of speaking; because the woman is neither the head of a family, nor brings forth properly for herself, but for her husband. What follows, however, is more worthy of notice, In his old age, at the set time, which God had predicted: for the old age of Abraham does, not a little, illustrate the glory of the miracle. And now Moses, for the third time, recalls us to the word of God, that the constancy of his truth may always be present to our minds. And though the time had been predicted, alike to Abraham and to his wife, yet this honor is expressly attributed to the holy man; because the promise had been especially given on his account. Both, however, are distinctly mentioned in the context.

3. And Abraham called the name. Moses does not mean that Abraham was the inventor of the name; but that he adhered to the name which before had been given by the angel. This act of obedience, however, was worthy of commendation, since he not only ratified the word of God, but also executed his office as God’s minister. For, as a herald, he proclaimed to all, that which the angel had committed to his trust.
