15:10 And he took unto him all these, and {c} divided them in the midst, and laid each piece one against another: but the birds divided he not.
(c) This was the old custom in making covenants, Jer 39:18, to which God added these conditions, that Abram's posterity would be as torn in pieces, but after they would be rejoined: also that it would be assaulted, but yet delivered.
15:7-11 Assurance was given to Abram of the land of Canaan for an inheritance. God never promises more than he is able to perform, as men often do. Abram did as God commanded him. He divided the beasts in the midst, according to the ceremony used in confirming covenants, Jer 34:18,19. Having prepared according to God's appointment, he set himself to wait for the sign God might give him. A watch must be kept upon our spiritual sacrifices. When vain thoughts, like these fowls, come down upon our sacrifices, we must drive them away, and seek to attend on God without distraction.
