Exodus 13:15 And when he hardened Pharaoh to send us, the lord slew all the first-born in the land of Egypt, from the first-born of men, unto the first-born of cattle. On account of this I sacrifice to the lord every offspring opening the womb, the males to the lord, and every first-born of my sons I will ransom.
