'Tenth' in the Bible

and Abraham gave him a tenth of everything;first, his name means king of righteousness,then also, king of Salem,meaning king of peace;

Now consider how great this man was—even Abraham the patriarch gave a tenth of the plunder to him!

The sons of Levi who receive the priestly office have a command according to the law to collect a tenth from the people—that is, from their brothers—though they have also descended from Abraham.
