'Thousands' in the Bible

And Solomon saith to all Israel, to heads of the thousands, and of the hundreds, and to judges, and to every honourable one of all Israel, heads of the fathers,

And these are their numbers, for the house of their fathers: Of Judah, heads of thousands, Adnah the head, and with him mighty ones of valour, three hundred chiefs.

And Amaziah gathereth Judah, and appointeth them, according to the house of the fathers, for heads of the thousands, and for heads of the hundreds, for all Judah and Benjamin; and he inspecteth them from a son of twenty years and upward, and findeth them three hundred thousand chosen ones, going forth to the host, holding spear and target.
