'Three score' in the Bible

And afterward Hezron went in to the daughter of Machir the father of Gilead, whom he married when he was threescore years old; and she bare him Segub.

And he took Geshur, and Aram, with the towns of Jair, from them, with Kenath, and the towns thereof, even threescore cities. All these belonged to the sons of Machir the father of Gilead.

The sons of Reuben, and the Gadites, and half the tribe of Manasseh, of valiant men, men able to bear buckler and sword, and to shoot with bow, and skilful in war, were four and forty thousand seven hundred and threescore, that went out to the war.

And their brethren, heads of the house of their fathers, a thousand and seven hundred and threescore; very able men for the work of the service of the house of God.

And Obededom with their brethren, threescore and eight; Obededom also the son of Jeduthun and Hosah to be porters:

And Joab gave the sum of the number of the people unto David. And all they of Israel were a thousand thousand and an hundred thousand men that drew sword: and Judah was four hundred threescore and ten thousand men that drew sword.

All these of the sons of Obededom: they and their sons and their brethren, able men for strength for the service, were threescore and two of Obededom.
