The nations oppressing the people of Judah severely is spoken of as if no person in Judah was able to raise his head. Alternate translation: "and caused them to suffer greatly" (See: [[rc://en/ta/man/translate/figs-metaphor]])
Yahweh speaks of the nations using their military power to conquer Judah as if the nations had lifted up their horns. He speaks of these four craftsmen destroying the military power of these nations as if the craftsmen threw those horns to the ground. Alternate translation: "to destroy the power of the nations who used their military might against the land of Judah" (See: [[rc://en/ta/man/translate/figs-metaphor]])
