Yehezkiel 44:20

44:20 “‘They must not shave their heads ¹  nor let their hair grow long; ²  they must only trim their heads.

Imamat 21:5

21:5 Priests ³  must not have a bald spot shaved on their head, they must not shave the corner of their beard, and they must not cut slashes in their body. ⁴ 

Yesaya 7:20

7:20 At that time ⁵  the sovereign master will use a razor hired from the banks of the Euphrates River, ⁶  the king of Assyria, to shave the head and the pubic hair; ⁷  it will also shave off the beard.

[44:20]  ¹ sn The shaving of the head was associated with mourning (Ezek 7:18).

[44:20]  ² sn Letting the hair grow was associated with the taking of a vow (Num 6:5; Acts 21:23-26).

[21:5]  ³ tn Heb “they”; the referent (priests, see the beginning of v. 1) has been specified in the translation for clarity.

[21:5]  ⁴ tn Heb “and in their body they shall not [cut] slash[es]” (cf. Lev 19:28). The context connects these sorts of mutilations with mourning rites (cf. Lev 19:27-28 above).

[7:20]  ⁵ tn Heb “in that day” (so ASV, NASB); KJV “In the same day.”

[7:20]  ⁶ tn Heb “the river” (so KJV); NASB “the Euphrates.” The name of the river has been supplied in the present translation for clarity.

[7:20]  ⁷ tn Heb “the hair of the feet.” The translation assumes that the word “feet” is used here as a euphemism for the genitals. See BDB 920 s.v. רֶגֶל.
