Charles Ellicott Commentary Hosea 1:11

"And the children of Judah and the children of Israel shall be gathered together, and they shall appoint themselves one head, and shall go up from the land; for great shall be the day of Jezreel." — Hosea 1:11 (ASV)

Shall come up out of the land.—This is better understood as shall go up out of, etc., a phrase that frequently occurs in Scripture to denote marching forth to war.

Israel shall then be united, and the envy of Israel and Judah shall cease (Isaiah 11:12–13; Ezekiel 34:24; Ezekiel 37:24). A worldwide dominion shall be established under the restored theocracy.

Regarding the word “land,” the prophet makes no reference to exile in Babylon, Assyria, or Egypt; Palestine is evidently meant. Then the true Israel, having chosen their true king, shall demonstrate the greatness of the day of Jezreel. The brothers and sisters will then drop the curse involved in their names and recognize the divine proprietorship of Jehovah and the abundance of His pity.
