Genesis 15:11

And when the fowls came down upon the carcases, Abram drove them away.

And when the fowls came down upon the carcass. The Septuagint interpolates a clause here [epi ta soomata, epi ta dichotomeemata autoon], upon the carcasses, upon their severed portions [kai sunekathisen autois Abram), and Abram sat along with them.] These birds of prey have been generally viewed as symbols of the affliction of Abram's posterity in Egypt, and of their deliverance.
