Exo Exodus, chapter Book of Exodus, chapter 13
And it came to pass, when Par’oh [Pharaoh - Great House] would hardly let us go, that the LORD-Yehōvah (Messiah Pre-Incarnate) killed all the firstborn in the land of Mitzrayim [Egypt - The Narrow Place], both the firstborn of man, and the firstborn of beast: therefore I sacrifice to the LORD-Yehōvah (Messiah Pre-Incarnate) all that opens the womb, being males; but all the firstborn of my children I redeem.Exo 4:23; Exo 12:29
