'Census' in the Bible

Joab gave the number of the census of all the people to David. And all Israel were 1,100,000 men who drew the sword; and Judah was 470,000 men who drew the sword.

The Levites were numbered from thirty years old and upward, and their number by census of men was 38,000.

These were the sons of Levi according to their fathers’ households, even the heads of the fathers’ households of those of them who were counted, in the number of names by their census, doing the work for the service of the house of the Lord, from twenty years old and upward.
