Worshipers presented the "peace offering of thanksgiving" to show gratitude to the Lord (Leviticus 7:12–15). This was unlike the vow offering linked to a promise made by a worshiper. After, they celebrated with a meal. The meal was less formal and could continue into the next day. But since the vow offering involved a promise to God, it had stricter rules than the voluntary offering, which could even use a deformed animal (22:23).
