Exodus 13:15-17

Amplified Bible, Classic Edition

¹⁵ For when Pharaoh stubbornly refused to let us go, the Lord slew all the firstborn in the land of Egypt, both the firstborn of man and of livestock. Therefore I sacrifice to the Lord all the males that first open the womb; but all the firstborn of my sons I redeem.

¹⁶ And it shall be as a reminder upon your hand or as frontlets between your eyes, for by a strong hand the Lord brought us out of Egypt.

¹⁷ When Pharaoh let the people go, God led them not by way of the land of the Philistines, although that was nearer; for God said, Lest the people change their purpose when they see war and return to Egypt.
