2 Chronicles 31:3-7

He also appointed the king’s portion of his property for the burnt offerings, namely, for the morning and evening burnt offerings, and the burnt offerings for the Sabbaths and for the new moons and for the appointed festivals, as it is written in the Law of the Lord.

Also he told the people who lived in Jerusalem to give the portion due to the priests and the Levites, so that they might devote themselves to the Law of the Lord.

As soon as the order spread, the sons of Israel abundantly provided the first fruits of grain, new wine, oil, honey, and of all the produce of the field; and they brought in abundantly the tithe of everything.

The sons of Israel and Judah who lived in the cities of Judah also brought in the tithe of oxen and sheep, and the tithe of sacred gifts which were consecrated to the Lord their God, and placed them in heaps.

In the third month they began to make the heaps, and they finished them by the seventh month.
