Leviticus 24:5–9 (NLT) — 5 “You must bake twelve flat loaves of bread from choice flour, using four quarts of flour for each loaf. 6 Place the bread before the LORD on the pure gold table, and arrange the loaves in two stacks, with six loaves in each stack. 7 Put some pure frankincense near each stack to serve as a representative offering, a special gift presented to the LORD. 8 Every Sabbath day this bread must be laid out before the LORD as a gift from the Israelites; it is an ongoing expression of the eternal covenant. 9 The loaves of bread will belong to Aaron and his descendants, who must eat them in a sacred place, for they are most holy. It is the permanent right of the priests to claim this portion of the special gifts presented to the LORD.”
Exodus 27:20–21 (NLT) — 20 “Command the people of Israel to bring you pure oil of pressed olives for the light, to keep the lamps burning continually. 21 The lampstand will stand in the Tabernacle, in front of the inner curtain that shields the Ark of the Covenant. Aaron and his sons must keep the lamps burning in the LORD’s presence all night. This is a permanent law for the people of Israel, and it must be observed from generation to generation.
Exodus 30:7–9 (NLT) — 7 “Every morning when Aaron maintains the lamps, he must burn fragrant incense on the altar. 8 And each evening when he lights the lamps, he must again burn incense in the LORD’s presence. This must be done from generation to generation. 9 Do not offer any unholy incense on this altar, or any burnt offerings, grain offerings, or liquid offerings.
