This verse summarizes the message that Amos received from the Lord. Amos reported that Yahweh roared from Zion, as a lion roars before it devours its prey or as thunder precedes a severe storm (cf. 3:4, 8; Jer. 25:30; Hos. 5:14; 11:10; 13:7). Yahweh was about to judge. "Yahweh"is the first word in the Hebrew sentence--usually a verb comes first--and so is emphatic by position. The Lord spoke from Zion (Jerusalem, also emphatic by position) because that is where He manifested Himself in a localized sense to the Israelites of Amos' day. In Israel, the primary worship centers were Dan and Bethel (1 Kings 12-13). All the land would mourn, from the shepherds' pastures in the lowland to the summit of Mt. Carmel (a merism), because the Lord would dry up the land. This was one of the promises of judgment if God's people proved unfaithful to His covenant with them, the Mosaic Covenant (Deut. 28:20-24; cf. Lev. 26:22; Deut. 32:24). "Yahweh"was God's covenant name, and it connotes holiness and power (cf. Exod. 3:5; 19:10-25). However, since oracles announcing judgment on neighbor nations, as well as on Israel, follow, the extent of God's judgment would go beyond Israel's territory and Israel's covenant (cf. Isa. 24:4-6; 26:20-21). The mention of Mt. Carmel, nevertheless, fixes the primary site in Israel. Most of this book records messages of judgment against Israel. So the theme of the book is practical righteousness (cf. James).
