Dough: First of, offered to God
Source: Nav
Numbers 15:19–21
and you eat the food of the land, you shall lift up an offering to the LORD. / From the first of your dough, you are to lift up a cake as a contribution; offer it just like an offering from the threshing floor. / Throughout your generations, you are to give the LORD an offering from the first of your dough.
Nehemiah 10:37
Moreover, we will bring to the priests at the storerooms of the house of our God the firstfruits of our dough, of our grain offerings, of the fruit of all our trees, and of our new wine and oil. A tenth of our produce belongs to the Levites, so that they shall receive tithes in all the towns where we labor.
