Charles Ellicott Commentary Hosea 11:10

"They shall walk after Jehovah, who will roar like a lion; for he will roar, and the children shall come trembling from the west." — Hosea 11:10 (ASV)

A rendering is: They shall go up after Jehovah, who roars as a lion; yea, he shall roar so that the children, etc. Lions accompanied Egyptian monarchs to the battlefield. Read the picturesque description of Rameses II in his battle with the Kheta, by George Ebers in Uarda. “West” means the coast and islands of the Levant.

Tremble — i.e., come with an awe-stricken joy to the voice of the Divine summons.
