8 On that day explain to your son, ‘This is because of what the Lord did for me when I came out of Egypt.’(A)
9 Let it serve as a sign for you on your hand and as a reminder on your forehead,(a)(B) so that the Lord’s instruction may be in your mouth; for the Lord brought you out of Egypt with a strong hand.
