Exodus 30:20-30

20 When they go into the tent of meeting, or when they come near the altar to minister, to burn an offering by fire to the LORD, they shall wash with water, lest they die.
21 They shall wash their hands and their feet, lest they die: it shall be a statute for ever to them, even to him and to his descendants throughout their generations."
22 Moreover, the LORD said to Moses,
23 "Take the finest spices: of liquid myrrh five hundred shekels, and of sweet-smelling cinnamon half as much, that is, two hundred and fifty, and of aromatic cane two hundred and fifty,
24 and of cassia five hundred, according to the shekel of the sanctuary, and of olive oil a hin;
25 and you shall make of these a sacred anointing oil blended as by the perfumer; a holy anointing oil it shall be.
26 And you shall anoint with it the tent of meeting and the ark of the testimony,
27 and the table and all its utensils, and the lampstand and its utensils, and the altar of incense,
28 and the altar of burnt offering with all its utensils and the laver and its base;
29 you shall consecrate them, that they may be most holy; whatever touches them will become holy.
30 And you shall anoint Aaron and his sons, and consecrate them, that they may serve me as priests.
