Exodus 13:16 New English Translation

¹⁶It will be for a sign on your hand and for frontlets^[a] on your forehead, for with a mighty hand the Lord brought us out of Egypt.”^[b]

Exodus 13:16 tn The word is טוֹטָפֹת (totafot, “frontlets”). The etymology is uncertain, but the word denotes a sign or an object placed on the forehead (see m. Shabbat 6:1). The Gemara interprets it as a band that goes from ear to ear. In the Targum to 2 Sam 1:10 it is an armlet worn by Saul (see S. R. Driver, Exodus, 110). These bands may have resembled the Egyptian practice of wearing as amulets “forms of words written on folds of papyrus tightly rolled up and sewn in linen” (W. C. Kaiser, Jr., “Exodus,” EBC 2:384).
Exodus 13:16 sn The pattern of the passage now emerges more clearly; it concerns the grateful debt of the redeemed. In the first part eating the unleavened bread recalls the night of deliverance in Egypt, and it calls for purity. In the second part the dedication of the firstborn was an acknowledgment of the deliverance of the firstborn from bondage. They were to remember the deliverance and choose purity; they were to remember the deliverance and choose dedication. The NT will also say, “You are not your own, for you were bought with a price, therefore, glorify God” (1 Cor 6:20). Here too the truths of God’s great redemption must be learned well and retained well from generation to generation.
