Yahweh has sworn by the pride of Jacob

Will not the land quake for this, and every one who lives in it mourn?

Amos uses a question to emphasize that these things will certainly happen. AT: "Yahweh will cause the land to shake, and every one who lives in it will mourn." (See: rc://en/ta/man/translate/figs-rquestion)
