Deuteronomy 16:8 In-Context

6 but at the place where the Lord your God chooses to make His name abide, there you shall sacrifice the Passover at twilight, at the going down of the sun, at the time you came out of Egypt.
7 And you shall roast and eat it in the place which the Lord your God chooses, and in the morning you shall turn and go to your tents.
8 Six days you shall eat unleavened bread, and on the seventh day there shall be a sacred assembly to the Lord your God. You shall do no work on it.
9 "You shall count seven weeks for yourself; begin to count the seven weeks from the time you begin to put the sickle to the grain.
10 Then you shall keep the Feast of Weeks to the Lord your God with the tribute of a freewill offering from your hand, which you shall give as the Lord your God blesses you.
