Exodus 10:25-27

Darby Translation

²⁵ And Moses said, Thou must give also sacrifices and burnt-offerings into our hands, that we may sacrifice to Jehovah our God.

²⁶ Our cattle also must go with us: there shall not a hoof be left behind; for we must take thereof to serve Jehovah our God; and we do not know with what we must serve Jehovah, until we come there.

²⁷ But Jehovah made Pharaoh's heart stubborn, and he would not let them go.
