Barnes New Testament Notes

Verse 73. The oath {q}. This oath is recorded in Ge 22:16,17. It was an oath in which God swore by himself (because he could swear by no greater, Heb 6:13,14) that he would surely bless Abraham and his posterity. That promise was now to be entirely fulfilled by the coming of the Messiah.
