Exodus 13:15-17

Darby Translation

¹⁵ And it came to pass, when Pharaoh stubbornly refused to let us go, that Jehovah slew all the firstborn in the land of Egypt, both the firstborn of men and the firstborn of cattle: therefore I sacrifice to Jehovah all that breaketh open the womb—being males; and every firstborn of my children I ransom.

¹⁶ And it shall be for a sign on thy hand, and for frontlets between thine eyes, for with a powerful hand Jehovah brought us forth out of Egypt.

¹⁷ And it came to pass, when Pharaoh let the people go, that God did not lead them the way of the land of the Philistines, although that was near; for God said, That the people may not repent when they see conflict, and return to Egypt.
