And the LORD visited Sarah as he had said, and the LORD did unto Sarah as he had spoken.
The Lord visited Sarah. The phrase, "the Lord visited," when used in Scripture with reference to a person or a people, indicates some signal token of favour-some remarkable blessing (cf. Exodus 3:16; 1 Samuel 2:21; Luke 1:68). The language of the historian seems designedly chosen to magnify the power of God, as well as His faithfulness to His promise. It was God's grace that brought about that event, as well as the raising of spiritual children to Abraham, of which the birth of this son was typical (Calvin).
