'Anointing oil' in the Bible

"Take Aaron, his sons with him, the clothing, the anointing oil, the bull for sin offering, two rams, and a basket of unleavened bread

After this, Moses took the anointing oil and anointed the tent, consecrating everything that was in it.

Moses took some anointing oil and blood that was on the altar and sprinkled it on Aaron, on his clothes, on his sons, and on their clothes, consecrating Aaron, his clothes, his sons, and their clothes.

Also, you are not to leave the entrance to the Tent of Meeting. Otherwise, you'll die, since the LORD's anointing oil remains on you." So they followed Moses' instructions.
