Exodus 28:38; Exodus 29:42; Exodus 30:8

38 And it shall be upon Aaron's forehead, that Aaron may bear the iniquity of the holy things, which the children of Israel shall hallow in all their holy gifts; and it shall be always upon his forehead, that they may be accepted before the LORD.

42 This shall be a continual burnt offering throughout your generations at the door of the tabernacle of the congregation before the LORD: where I will meet you, to speak there unto thee.

8 And when Aaron lighteth the lamps at even, he shall burn incense upon it, a perpetual incense before the LORD throughout your generations.
