Ulangan 6:8

6:8 You should tie them as a reminder on your forearm ¹  and fasten them as symbols ²  on your forehead.

Ulangan 27:8

27:8 You must inscribe on the stones all the words of this law, making them clear.”

Ulangan 33:25

33:25 The bars of your gates ³  will be made of iron and bronze,

and may you have lifelong strength.

[6:8]  ¹ sn Tie them as a sign on your forearm. Later Jewish tradition referred to the little leather containers tied to the forearms and foreheads as tefillin. They were to contain the following passages from the Torah: Exod 13:1-10, 11-16; Deut 6:5-9; 11:13-21. The purpose was to serve as a “sign” of covenant relationship and obedience.

[6:8]  ² sn Fasten them as symbols on your forehead. These were also known later as tefillin (see previous note) or phylacteries (from the Greek term). These box-like containers, like those on the forearms, held the same scraps of the Torah. It was the hypocritical practice of wearing these without heartfelt sincerity that caused Jesus to speak scathingly about them (cf. Matt 23:5).

[33:25]  ³ tn The words “of your gates” have been supplied in the translation to clarify the referent of “bars.”
