Nehemiah 10:30-33

30and that we would not give our daughters unto the peoples of the land, nor take their daughters for our sons:

31and if the peoples of the land bring ware or any victuals on the sabbath day to sell, that we would not buy of them on the sabbath, or on a holy day: and that we would forgo the seventh year, and the exaction of every debt.

32Also we made ordinances for us, to charge ourselves yearly with the third part of a shekel for the service of the house of our God;

33for the shewbread, and for the continual meal offering, and for the continual burnt offering, of the sabbaths, of the new moons, for the set feasts, and for the holy things, and for the sin offerings to make atonement for Israel, and for all the work of the house of our God.
