The words of Amos, who was among the herdsmen of Tekoa, which he saw concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash king of Israel, two years before the earthquake.
"In this [ancient Near Eastern] culture an earthquake would not have been viewed as a mere natural occurrence, but as an omen of judgment. Amos had warned that the Lord would shake the earth (see Amos 8:8; Amos 9:1; Amos 9:5, as well as Amos 4:12-13). When the earthquake occurred just two years after he delivered his message, it signaled that the Lord was ready to make the words of Amos a reality." [Note: Robert B. Chisholm Jr., Handbook on the Prophets, p. 378.]
