The LORD responded, "Bring me a three-year-old cow, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon."

Then one of them said, "I will certainly return to you in about a year's time. By then, your wife Sarah will have borne a son."

Abraham fell to the ground, laughed, and told himself, "Can a child be born to a 100-year-old man? Can a 90-year-old Sarah give birth?"
