'Years' in the Bible

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

six were born unto him in Hebron; and there he reigned seven years and six months. And in Jerusalem he reigned thirty and three years;

either three years of famine; or three months to be consumed before thy foes, while the sword of thine enemies overtaketh thee; or else three days the sword of Jehovah, even pestilence in the land, and the angel of Jehovah destroying throughout all the borders of Israel. Now therefore consider what answer I shall return to him that sent me.

And the Levites were numbered from thirty years old and upward: and their number by their polls, man by man, was thirty and eight thousand.

These were the sons of Levi after their fathers houses, even the heads of the fathers houses of those of them that were counted, in the number of names by their polls, who did the work for the service of the house of Jehovah, from twenty years old and upward.

For by the last words of David the sons of Levi were numbered, from twenty years old and upward.

But David took not the number of them from twenty years old and under, because Jehovah had said he would increase Israel like to the stars of heaven.

And the time that he reigned over Israel was forty years; seven years reigned he in Hebron, and thirty and three years reigned he in Jerusalem.
