Exodus 10:25-27

American Standard Version

²⁵ And Moses said, Thou must also give into our hand sacrifices and burnt-offerings, that we may sacrifice unto Jehovah our God. ²⁶ Our cattle also shall go with us; there shall not a hoof be left behind; for thereof must we take to serve Jehovah our God; and we know not with what we must serve Jehovah, until we come thither. ²⁷ But Jehovah ^[a]hardened Pharaoh’s heart, and he would not let them go.
