Exodus 6:8  (King James Version)
And I will bring you in unto the land, concerning the which I did swear to give it to Abraham, to Isaac, and to Jacob; and I will give it you for an heritage: I am the LORD.

as a verb, to take an oath. A similar custom prevailed among the heathens See Virg. n. 1. xii. v. 196.
