Matthew Poole and continuators on Exodus 13:16

16 And it shall be for a token upon thine hand, and for frontlets between thine eyes: For by strength of hand the LORD brought us forth out of Egypt.

In stead of frontlets. The sence is, This practice shall make your deliverance from Egypt as fresh and evident to you and to your children as any thing which you see hanged or written upon one anothers foreheads. See Ezek. 9. 4. It seems strange to me, that they that understand the sign on the hand, and the memorial between the eyes, ver. 9. metaphorically should understand the frontlets between the eyes in this place properly, seeing the phrase is perfectly the same; onely here is a more particular allusion to the custom of the Egyptians, which used to wear some devices upon their foreheads, which probably, they called totaphot[illegible: 1+ letters], which were memorials of their Idols, or of something relating to them. And therefore it seems unlikely that he would here prescribe the use of the same things to the Iews, and the more probable meaning of the phrase is onely this, that this practice would be as effectual and useful a remembrancer of this mighty and glorious work of God in bringing them out of Egypt as those contrivances were to the Egyptians of their Idols.
