'Tenth' in the Bible

to whom also Abraham apportioned a tenth of everything--in the first place, [his name] is translated "king of righteousness," and then also "king of Salem," that is, "king of peace";

But see how great this man [was], to whom Abraham the patriarch gave a tenth from the spoils!

And indeed those of the sons of Levi who receive the priesthood have a commandment to collect a tenth from the people according to the law, that is, from their brothers, although {they are descended from Abraham}.
