Exodus 13:15 YLT

¹³  'And every firstling of an ass thou dost ransom with a lamb, and if thou dost not ransom 'it', then thou hast beheaded it: and every first-born of man among thy sons thou dost ransom.

¹⁴  'And it hath been, when thy son asketh thee hereafter, saying, What 'is' this? that thou hast said unto him, By strength of hand hath Jehovah brought us out from Egypt, from a house of servants;

¹⁵  yea, it cometh to pass, when Pharaoh hath been pained to send us away, that Jehovah doth slay every first-born in the land of Egypt, from the first-born of man even unto the first-born of beast; therefore I am sacrificing to Jehovah all opening a womb who 'are' males, and every first-born of my sons I ransom;

¹⁶  and it hath been for a token on thy hand, and for frontlets between thine eyes, for by strength of hand hath Jehovah brought us out of Egypt.'

¹⁷  And it cometh to pass in Pharaoh's sending the people away, that God hath not led them the way of the land of the Philistines, for it 'is' near; for God said, 'Lest the people repent in their seeing war, and have turned back towards Egypt;'
