Charles Ellicott Commentary Zechariah 2:7

"Ho Zion, escape, thou that dwellest with the daughter of Babylon." — Zechariah 2:7 (ASV)

Daughter of Babylon means inhabitants of Babylon, as (Zechariah 2:10) “daughter of Zion” means inhabitants of Zion. (Compare the whole passage to Isaiah 48:20; Jeremiah 51:6; Jeremiah 51:9; Jeremiah 51:45.) Septuagint for “O Zion,” εὶς Σιῶν—compare to a somewhat similar mistake in Ezekiel 21:15 (Zechariah 2:10, Septuagint).
