What does Genesis 15:10 mean?
In response to Abram's request for reassurance that he and his offspring would possess the land as God had promised, the Lord told Abram to bring five specific animals before Him. Abram did so and now proceeds to cut the heifer, goat, and ram (all three years old) in half and to lay each half opposite the other. He did not cut the turtledove or pigeon in half.The symbolic meaning of this bloody-but-purposeful covenant ritual will be clarified in the following verses. In part, this meaning involves a unity of those making the agreement. According to some interpreters, this ritual was also used as a way of demonstrating sincerity; by implying that those passing between the pieces were willing to be destroyed, as the animals were, if they broke their part of the agreement. The use of the animals also provides Abram with a symbolic picture of Israel's future struggles under the oppressive rule of Egypt.
