And Isaac prayed to the LORD for his wife, because she was barren. And the LORD granted his prayer, and Rebekah his wife conceived.
21. And Isaac entreated the Lord for his wife. Some translate the passage, Isaac entreated the Lord in the presence of his wife; and understand this to have been done, that she also might add her prayers, and they might jointly supplicate God. But the version here given is more simple.
We have here an account of the birth of Jacob and Esau, the twin sons of Isaac and Rebekah: their entrance into the world was (which is not usual) one of the most considerable parts of their story; nor is much related concerning Isaac but what had reference to his father while he lived and to his sons afterwards.
Commenting on Genesis 25:19-28
And Isaac entreated the Lord for his wife,.... Was very earnest and constant in his supplications for her, as the word signifies, as is observed by Jarchi; or, "before his wife" (a), she being present, and joining with him in his prayers: the reason was: because she was barren; which appeared by the length of time they had been married, which was near twenty years, see Gen 25:26.
