Exodus 10:25 WBT

²³  They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings.

²⁴  And Pharaoh called to Moses, and said, Go ye, serve the LORD; only let your flocks and your herds be stayed: let your little ones also go with you.

²⁵  And Moses said, Thou must give us also sacrifices, and burnt-offerings, that we may sacrifice to the LORD our God.

²⁶  Our cattle also shall go with us; there shall not a hoof be left behind; for of them must we take to serve the LORD our God; and we know not with what we must serve the LORD, until we come thither.

²⁷  But the LORD hardened Pharaoh's heart, and he would not let them go.
