'Fifties' in the Bible

But for the rest, take from among the people able men, such as have the fear of God, true men hating profits wrongly made; and put such men over them, to be captains of thousands, captains of hundreds and of fifties and of tens;

And he made selection of able men out of all Israel, and made them heads over the people, captains of thousands, captains of hundreds and of fifties and of tens.
