'Fifties' in the Bible

But you should select from all the people able men, God-fearing, trustworthy, and hating bribes. Place them over the people as commanders of thousands, hundreds, fifties, and tens.

So Moses chose able men from all Israel and made them leaders over the people as commanders of thousands, hundreds, fifties, and tens.

“So I took the leaders of your tribes, wise and respected men, and set them over you as leaders: officials for thousands, hundreds, fifties, and tens, and officers for your tribes.

He can appoint them for his use as commanders of thousands or commanders of fifties, to plow his ground or reap his harvest, or to make his weapons of war or the equipment for his chariots.

Already fire has come down from heaven and consumed the first two captains of 50 with their fifties, but this time let my life be precious in your sight.”

So they sat down in ranks of hundreds and fifties.
