Nehemiah 10:30-33

30and that we will not give our daughters [as wives] to the peoples of the land or take their daughters for our sons.

31As for the peoples of the land who bring merchandise or any grain on the Sabbath day to sell, we will not buy from them on the Sabbath or on a holy day; and we will give up raising crops during the seventh year [leaving the land uncultivated], and forgive every debt.

32Also we pledge ourselves to contribute yearly one third of a shekel for the service [expenses] of the house of our God:

33for the showbread; for the continual grain offerings and the continual burnt offerings; [for the offerings on] the Sabbaths, the New Moons, the [feasts at] appointed times; for the holy things, for the sin offerings to make atonement for Israel; and for all the work of the house of our God.
