The LORD said to Moses,
"Command the people of Israel to provide you with pure olive oil for the lampstand, so it can be kept burning continually.
Aaron will set it up outside the inner curtain of the Most Holy Place in the Tabernacle and must arrange to have the lamps tended continually, from evening until morning, before the LORD. This is a permanent law for you, and it must be kept by all future generations.
References for Leviticus 24:3

References for Leviticus 24:5
Place the bread in the LORD's presence on the pure gold table, and arrange the loaves in two rows, with six in each row.
Sprinkle some pure frankincense near each row. It will serve as a token offering, to be burned in place of the bread as an offering given to the LORD by fire.
Every Sabbath day this bread must be laid out before the LORD on behalf of the Israelites as a continual part of the covenant.
The loaves of bread belong to Aaron and his male descendants, who must eat them in a sacred place, for they represent a most holy portion of the offerings given to the LORD by fire."
