'Old' 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.

Now David was old and full of days; and he made Solomon his son king over Israel.

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 he died in a good old age, full of days, riches, and honor: and Solomon his son reigned in his stead.
