Nehemiah 10:37

and that we will bring the dedications of our corn including the fruit of trees, and of wine and oil to the stores of the house of God for the priests; and the tithe of our land for the Levites. But the Levites themselves shall receive the tithes in all the cities of our bondage;

the first-born of our sons, and of our cattle, as it is written in the law, and the first-born of our herds and of our flocks, to bring to the house of our God, for the priests that minister in the house of our God.
