One thousand will flee at the threat of one; at the threat of five you will flee

The word "solider" is understood. Alternate translation: "One thousand soldiers will flee at the threat of one enemy soldier; at the threat of five enemy soldiers all of your soldiers will flee" (See: rc://en/ta/man/jit/figs-ellipsis)

One thousand

"1,000" (See: rc://en/ta/man/jit/translate-numbers)

until your remnant will be like a flagstaff on the top of a mountain, or like a signal flag on a hill

This simile means there will be so few people left that they will be like a single signal flag on top of a hill. (See: rc://en/ta/man/jit/figs-simile)

signal flag

See how you translated this in Isaiah 5:26.
