Leviticus 24:1-4

1 Oil and Bread Set Before the Lord
The Lord said to Moses,

2 “Command the Israelites to bring you clear oil of pressed olives for the light so that the lamps may be kept burning continually.

3 Outside the curtain of the Testimony in the Tent of Meeting, Aaron is to tend the lamps before the Lord from evening till morning, continually. This is to be a lasting ordinance for the generations to come.

4 The lamps on the pure gold lampstand before the Lord must be tended continually.
