AT: "the commanders of 100 soldiers" or 2) the word translated as "hundreds" does not represent an exact number, but is the name of a military division. AT: "the commanders of military divisions" See how you translated this in [2 Chronicles 23:1](./01.md). (See: [[rc://en/ta/man/translate/translate-numbers]])
