Numbers 15:2, 18-21

“Speak to the Israelites and say to them, ‘When you enter the land that I am giving you as a home

“Tell the Israelites: ‘You are going to another land, where I am taking you. When you eat the food there, offer part of it to the LORD. Offer a loaf of bread from the first of your grain, which will be your offering from the threshing floor. From now on offer to the LORD the first part of your grain.
