21 You are to work for six days; but when the seventh day arrives, you are to observe the Sabbath and rest. Even when it is the time to plow and harvest, you must still rest on the seventh day. 22 Also, you are to celebrate the Feast of Weeks, when the firstfruits from the wheat harvest are gathered. And when one year ends and another begins, celebrate the Ingathering Feast. 23 All your men are to appear before Me, the Lord and one True God of Israel, three times a year at these feasts.
