Nehemiah 10:30-33

30We will not give our daughters in marriage to the surrounding peoples and will not take their daughters as wives for our sons.

31When the surrounding peoples bring merchandise or any kind of grain to sell on the Sabbath day, we will not buy from them on the Sabbath or a holy day. We will also leave the land uncultivated in the seventh year and will cancel every debt.

32We will impose the following commands on ourselves: To give an eighth of an ounce of silver yearly for the service of the house of our God:

33the bread displayed before the Lord, the daily grain offering, the regular burnt offering, the Sabbath and New Moon offerings, the appointed festivals, the holy things, the sin offerings to atone for Israel, and for all the work of the house of our God.
