13:1 When members of the tribe of Ephraim spoke, the other Israelites trembled because they looked to Ephraim for leadership (cf. Judg. 8:1-3; 12:1-6). Jacob had prophesied that Ephraim would lead (Gen. 48:13-20), and the first king of the Northern Kingdom, Jeroboam I, had come from the tribe of Ephraim (1 Kings 11:26; 12:25). The Ephraimites exalted themselves in the North as well. Yet they were also the leaders in Baal worship. Therefore they were as good as dead since God would judge idolaters.
13:2 The Ephraimites, and the other Israelites, had continued to sin more and more by making molten images and carved idols of silver (cf. Exod. 20:4-5; 34:17; Deut. 5:8-9). They took great pains to make beautiful idols by employing skilled craftsmen for their construction. They also required that those who made sacrifices to them profess their devotion and homage by kissing the images.82How doubly ironical it was that they should worship things that they had created and that they should kiss images of animals!
13:3 Because they did this the Ephraimites would soon vanish from their land. They would disappear like fog or dew in the morning and like chaff from a threshing floor and smoke from a chimney that the wind blew away. Judgment would come swiftly and surely.
