Deuteronomy 16:22

Deuteronomy 16 commands Israel to observe the Passover in the month of Abib, the Feast of Weeks, and the Feast of Tabernacles at the place the Lord chooses, appearing before Him with freewill offerings and rejoicing. It instructs them to appoint judges and officers in every town to judge the people with righteous judgment, showing no partiality and taking no bribe. The chapter closes by forbidding them to plant a grove or set up any image beside the Lord's altar, which He hates.
