Matthew Henry's Complete Commentary - Genesis 21:1-8

Few under the Old Testament were brought into the world with such expectation as Isaac was, not for the sake of any great person eminence at which he was to arrive, but because he was to be, in this very thing, a type of Christ, that seed which the holy God had so long promised and holy men so long expected. In this account of the first days of Isaac we may observe, I. The fulfilling of God's promise in the conception and birth of Isaac, Gen. 21:1, 2. Note, God's providences look best and... read more

For Sarah conceived ,.... This explains what is meant by the Lord's visiting her, and doing to her according to his word, see Hebrews 11:11 , and bare Abraham a son in his old age ; which circumstance is remarked, that the favour might appear the greater, and the more wonderful; or, "unto", or "for his old age" F14 לזקניו "pro senectute ejus", Vatablus; "senectuti ejus", Junius & Tremellius. , for the comfort of him in his old age, who having lived so many years under the... read more

John Gills Exposition of the Bible Commentary - Genesis 21:3

And Abraham called the name of his son that was borne unto him, whom Sarah bare to him, Isaac. Which is the name he was directed to give him, Genesis 17:19 ; and he remembers the order, and is obedient to it; the reason of which name, which signifies laughter, was on account of his laughing for joy at the promise made him, as well as there might be afterwards a further reason for it, from Sarah's laughing through distrust; and it might presignify the joy and laughter that would be... read more

John Gills Exposition of the Bible Commentary - Genesis 21:4

And Abraham circumcised his son Isaac, being eight days old as , God had commanded him. Genesis 17:12 , and was the first that we read of that was circumcised on that day, according to the divine precept, which Abraham strictly observed; for though this was the son of the promise, and of his old age, for whom he had the most affectionate regard, yet he administered this bloody ordinance on him; nor did he defer it beyond the time, and was himself the operator, as it seems; all which... read more

John Gills Exposition of the Bible Commentary - Genesis 21:5

And Abraham was an hundred years old when son Isaac was born unto him. So that this was years after his departure from Haran, and coming into the land of Canaan, for then he was seventy five years of age, Genesis 12:4 ; and this exactly agrees with the account of Demetrius, as related by Polyhistor, an Heathen writer F15 Apud Euseb. Praepar. Evangel. l. 9. c. 21. p. 425. , who makes Isaac to be born just twenty five years from Abraham's coming into the land of Canaan, and who must be... read more

John Calvin's Commentary on the Bible - Genesis 21:2

Verse 2 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... read more

John Calvin's Commentary on the Bible - Genesis 21:3

Verse 3 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. read more

John Calvin's Commentary on the Bible - Genesis 21:4

Verse 4 4.And Abraham circumcised his son. Abraham pursued his uniform tenor of obedience, in not sparing his own son. For, although it would be painful for him to wound the tender body of the infant; yet, setting aside all human affection, he obeys the word of God. And Moses records that he did as the Lord had commanded him; because there is nothing of greater importance, than to take the pure word of God for our rule, and not to be wise above what is lawful. This submissive spirit is... read more
