Exodus

Let my prayer be set forth before thee as incense; and the lifting up of my hands as the evening sacrifice.

And they withstood Uzziah the king, and said unto him, It appertaineth not unto thee, Uzziah, to burn incense unto the Lord, but to the priests the sons of Aaron, that are consecrated to burn incense: go out of the sanctuary; for thou hast trespassed; neither shall it be for thine honour from the Lord God.

Behold, I build an house to the name of the Lord my God, to dedicate it to him, and to burn before him sweet incense, and for the continual shewbread, and for the burnt offerings morning and evening, on the sabbaths, and on the new moons, and on the solemn feasts of the Lord our God. This is an ordinance for ever to Israel.

According to the custom of the priest’s office, his lot was to burn incense when he went into the temple of the Lord.

And did I choose him out of all the tribes of Israel to be my priest, to offer upon mine altar, to burn incense, to wear an ephod before me? and did I give unto the house of thy father all the offerings made by fire of the children of Israel?
