'Upward' in the Bible

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

These were the sons of Levi according to their fathers' houses, the chief fathers, as they were reckoned, by number of names by their polls, who did the work of the service of the house of Jehovah, from twenty years old and upward.

For by the last words of David was this done, the numbering of the sons of Levi from twenty years old and upward.
