1 tc BHS suggests אֶתְכֶם (’etkhem, “you”) for the MT אֲבֹתֵיכֶם (’avotekhem, “your fathers”) to harmonize with v. 4. In v. 4 the ancestors would not turn but in v. 6 they appear to have done so. The subject in v. 6, however, is to be construed as Zechariah’s own listeners.
2 tn Heb “they turned” (so ASV). Many English versions have “they repented” here; cf. CEV “they turned back to me.”
