The fighting against the people of Ammon is spoken of as if it were a violent storm. AT: "and the fighting will be like a great storm" (See: [[rc://en/ta/man/translate/figs-metaphor]])
# tempest ... whirlwind
These are two kinds of violent storms.
# whirlwind
a strong wind that spins very quickly as it moves and can cause damage
# Their king will go into captivity
The abstract noun "captivity" can be translated as the verb "capture." This can be translated in active form. AT: "Their enemies will capture their king and take him away as a prisoner" (See: [[rc://en/ta/man/translate/figs-abstractnouns]] and [[rc://en/ta/man/translate/figs-activepassive]])
