Leviticus 24:1 MSG

[1] God spoke to Moses: “Order the People of Israel to bring you virgin olive oil for light so that the lamps may be kept burning continually. Aaron is in charge of keeping these lamps burning in front of the curtain that screens The Testimony in the Tent of Meeting from evening to morning continually before God. This is a perpetual decree down through the generations. Aaron is responsible for keeping the lamps burning continually on the Lampstand of pure gold before God.
