7 And he said to him, I am Jehovah who brought thee out of Ur of the Chaldeans, to give thee this land to possess it. 8 And he said, Lord Jehovah, how shall I know that I shall possess it? 9 And he said to him, Take me a heifer of three years old, and a she-goat of three years old, and a ram of three years old, and a turtle-dove, and a young pigeon. 10 And he took all these, and divided them in the midst, and laid the half of each opposite its fellow; but the birds he did not divide. 11 And the birds of prey came down on the carcases; and Abram scared them away.

Commentary on Genesis 15:7-11
(Read Genesis 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, Jeremiah 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.
