All of his refugees ... armies will fall by the sword

The word "fall" is a euphemism for "die." Here the word "sword" is a metonym for soldiers who kill people with swords. Alternate translation: "Soldiers will kill all his refugees ... armies" (See: rc://en/ta/man/jit/figs-metonymy)

the ones who remain will be scattered in every direction

This can be stated in active form. Alternate translation: "the ones who remain alive will flee in every direction" or "the enemy soldiers will scatter in every directions the ones who remain alive" (See: rc://en/ta/man/jit/figs-activepassive)

know that I am Yahweh

When Yahweh says that people will know that he is Yahweh, he is implying that they will know that he is the one true God who has supreme authority and power. See how you translated this in Ezekiel 6:7. Alternate translation: "understand that I am Yahweh, the one true God" or "realize that I, Yahweh, have supreme power and authority" (See: rc://en/ta/man/jit/figs-explicit)
