'Tenths' in the Bible

And to the children of Levi I have given as their heritage all the tenths offered in Israel, as payment for the work they do, the work of the Tent of meeting.

For the tenths which the children of Israel give as a lifted offering to the Lord I have given to the Levites as their heritage. and so I have said to them, Among the children of Israel they will have no heritage.

So you are to make an offering lifted up to the Lord from all the tenths which you get from the children of Israel, giving out of it the Lord's lifted offering to Aaron the priest.
