1 Chronicles 23:29-31

Living Bible

²⁹ They provided the Bread of the Presence, the flour for the grain offerings, and the wafers made without yeast (either fried or mixed with olive oil); they also checked all the weights and measures. ³⁰ Each morning and evening they stood before the Lord to sing thanks and praise to him. ³¹ They assisted in the special sacrifices of burnt offerings, the Sabbath sacrifices, the new moon celebrations, and at all the festivals. There were always as many Levites present as were required for the occasion.
