New Defender's Study Bible Notes
1:2 roar from Zion. As in many of the prophecies, there often is both a near fulfillment and a far fulfillment in view. The use of “roar” in this type of context usually looks forward to the great “day of the Lord” (Zechariah 14:1) yet to come in the last days (compare Isaiah 42:13; Jeremiah 25:30; Joel 3:16; etc., especially the latter).
1:2 his voice from Jerusalem. Even though Amos was in Israel at Bethel (Amos 7:10-13), he knew that God would center His work at Jerusalem, when He would “roar out of Zion.”
