Thou shouldest have brought guiltiness upon us - It is likely that Abimelech might have had some knowledge of God's intentions concerning the family of Abraham, and that it must be kept free from all impure and alien mixtures; and that consequently, had he or any of his people taken Rebekah, the Divine judgment might have fallen upon the land. Abimelech was a good and holy man; and he appears to have considered adultery as a grievous and destructive crime.

And Abimelech said, what is this thou hast done unto us?.... By entertaining suspicions and jealousies of us as bad men, and by exposing us to the temptation of committing iniquity; why hast thou dealt thus with us, and what have we done, or is in our character, that thou shouldest act after this manner?

one of the people might lightly have lien with thy wife; it is much one or other had not before this time, not looking upon it criminal to have to do with a single woman, when they would not have meddled with another man's wife, Jarchi interprets this of Abimelech himself; and so the Targum of Jonathan, who perhaps had been thinking of taking her to his bed; and was "within a little" (c), as the word for "lightly" may be rendered, of accomplishing his design:

and thou shouldest have brought guiltiness upon us: been the occasion of their committing the sin of adultery, which was heinous in the eyes of Heathens, and of bringing on them the punishment due thereunto.

(c) "parum abfuit", Junius & Tremellius, Piscator, Schmidt.

And Abimelech said, What is this thou hast done unto us? one of the people might lightly have lien with thy wife, and thou shouldest have brought {f} guiltiness upon us.

(f) In all ages men were persuaded that God's vengeance would come on adulterers.

26:10 Lightly - Perhaps.

26:6-11 There is nothing in Isaac's denial of his wife to be imitated, nor even excused. The temptation of Isaac is the same as that which overcame his father, and that in two instances. This rendered his conduct the greater sin. The falls of those who are gone before us are so many rocks on which others have split; and the recording of them is like placing buoys to save future mariners. This Abimelech was not the same that lived in Abraham's days, but both acted rightly. The sins of professors shame them before those that are not themselves religious.
