'Reckoned' in the Bible

And my God put into my heart to gather together the nobles, and the rulers, and the people, that they might be reckoned by genealogy. And I found the book of the genealogy of them that came up at the first, and I found written therein:

These sought their register among those that were reckoned by genealogy, but it was not found: therefore were they deemed polluted and put from the priesthood.
