For Sarah conceived,…. This explains what is meant by the Lord’s visiting her, and doing to her according to his word, see
Heb 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” n, for the comfort of him in his old age, who having lived so many years under the promise of a son, and in the expectation of one, even of the promised seed, from whom the Messiah should spring, now has one, than which nothing could yield him greater consolation:
at the set time of which God had spoken to him, Ge 17:21; God was not only faithful in fulfilling his promise, but in keeping the exact time of it.

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.

Gen 21:2, &c. Sarahbare Abraham a son, &c. Isaac at last is born; the wonder and expectation of his day. Observe,
1. The fulfilment of the promise, when all human prospects were at an end; when Abraham was as dead, and Sarah past the time of child-bearing. Note; (1.) Promised mercies will come in God’s time. (2.) God can work for us, when we most despair of ourselves. (3.) What nature cannot do, faith can, Heb 11:11.
2. Abraham’s carefulness to observe God’s prescribed order, to circumcise him on the eighth day, and give him the name of Isaac. Note; When our hearts are circumcised, and our new name given us, as sons of Abraham, Isaac’s, sons of laughter, then shalt we rejoice with joy unspeakable and full of glory.

For Sarah conceived, and bare Abraham a son in his old age, at the set time of which God had spoken to him.
Observe here, that it is twice mentioned by the Holy Ghost, as if to impress it more strongly on the mind, that this event, so contrary to the ordinary course of nature, was, as the Lord had said (Gen 21:1 ) and as the Lord had spoken, (Gen 21:2 )
