Zechariah 3:1 New English Translation

3 Next I saw Joshua the high priest^[a] standing before the angel of the Lord, with Satan^[b] standing at his right hand to accuse him.

Zechariah 3:1 sn Joshua the high priest mentioned here is the son of the priest Jehozadak, mentioned also in Hag 1:1 (cf. Ezra 2:2; 3:2, 8; 4:3; 5:2; 10:18; Neh 7:7; 12:1, 7, 10, 26). He also appears to have been the grandfather of the high priest contemporary with Nehemiah ca. 445 b.c. (Neh 12:10).
Zechariah 3:1 tn The Hebrew term הַשָּׂטָן (hassatan, “the satan”) suggests not so much a personal name (as in almost all English translations) but an epithet, namely, “the adversary.” This evil being is also described this way in Job 1 and 2 and possibly 1 Chr 21:1.
