'Sixty' in the Bible

Afterward Hezron went in to the daughter of Machir the father of Gilead, whom he took [as wife] when he was sixty years old; and she bore him Segub.

Geshur and Aram took the towns of Jair from them, with Kenath, and its villages, even sixty cities. All these were the sons of Machir the father of Gilead.

The sons of Reuben, and the Gadites, and the half-tribe of Manasseh, of valiant men, men able to bear buckler and sword, and to shoot with bow, and skillful in war, were forty-four thousand seven hundred and sixty, that were able to go forth to war.

and their brothers, heads of their fathers' houses, one thousand seven hundred sixty; very able men for the work of the service of the house of God.
