12 I will pass along, therefore, throughout the land of Egypt this night, and will smite every firstborn in the land of Egypt, from man even to beast,and against all the gods of Egypt, will I execute judgmentsI, Yahweh.13 Then shall the blood serve you for a sign, on the houses wherein ye are, then will I behold the blood, and will pass over you,and there shall be among you no plague to destroy, when I smite the laud of Egypt.
