Matthew Poole and continuators on Genesis 16:2

2. And Sarai said unto Abram, Behold now, the LORD hath restrained me from bearing, I pray thee go in unto my maid: it may be that I may obtain children by her . and Abram hearkned to the voice of Sarai .

She reckons the children of her bond-woman, (as Hagar was, Gal. 4. 22.) would be accounted her children. See Gen. 30. 3. Exod. 21. 4. 2 Sam. 21. 8. Esth. 2. 7.

Supposing that God would accomplish his promise of a seed to come out of his loyns by this way; and knowing that Sarai was not yet mentioned in the promise, as the person by whom he should have that seed; and not consulting with God, which he should have done.

Marginal references: Heb. be builded by her.
