Genesis 15:4-10
English Standard Version
Chapter 15
4And behold, the word of the Lord came to him: "This man shall not be your heir; your very own son shall be your heir." 5And he brought him outside and said, "Look toward heaven, and number the stars, if you are able to number them." Then he said to him, "So shall your offspring be." 6And he believed the Lord, and he counted it to him as righteousness.
7And he said to him, "I am the Lord who brought you out from Ur of the Chaldeans to give you this land to possess."
8But he said, "O Lord God, how am I to know that I shall possess it?"
9He said to him, "Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon."
10And he brought him all these, cut them in half, and laid each half over against the other. But he did not cut the birds in half.
