Doctrine and Covenants 13:1 Upon you my fellow servants, in the name of Messiah I confer the Priesthood of Aaron, which holds the keys of the ministering of angels, and of the gospel of repentance, and of baptism by immersion for the remission of sins; and this shall never be taken again from the earth, until the sons of Levi do offer again an offering unto the Lord in righteousness.
Doctrine and Covenants 20:73 The person who is called of God and has authority from Jesus Christ to baptize, shall go down into the water with the person who has presented himself or herself for baptism, and shall say, calling him or her by name: Having been commissioned of Jesus Christ, I baptize you in the name of the Father, and of the Son, and of the Holy Ghost. Amen.
Doctrine and Covenants 39:23 And again, it shall come to pass that on as many as ye shall baptize with water, ye shall lay your hands, and they shall receive the gift of the Holy Ghost, and shall be looking forth for the signs of my coming, and shall know me.
Doctrine and Covenants 68:8 Go ye into all the world, preach the gospel to every creature, acting in the authority which I have given you, baptizing in the name of the Father, and of the Son, and of the Holy Ghost.
Doctrine and Covenents, Section 84:
6 And the sons of Moses, according to the Holy Priesthood which he received under the chand of his father-in-law, Jethro;
7 And Jethro received it under the hand of Caleb;
9 And Caleb received it under the hand of Elihu;
9 And Elihu under the hand of Jeremy;
10 And Jeremy under the hand of Gad;
11 And Gad under the hand of Esaias;
12 And Esaias received it under the hand of God.
13 Esaias also lived in the days of Abraham, and was blessed of him
14 Which Abraham received the priesthood from Melchizedek, who received it through the lineage of his fathers, even till Noah;
15 And from Noah till Enoch, through the lineage of their fathers;
16 And from Enoch to Abel, who was slain by the conspiracy of his brother, who received the priesthood by the commandments of God, by the hand of his father Adam, who was the first man
17 Which priesthood continueth in the church of God in all generations, and is without beginning of days or end of years.
18 And the Lord confirmed a priesthood also upon Aaron and his seed, throughout all their generations, which priesthood also continueth and abideth forever with the priesthood which is after the holiest order of God.
19 And this greater priesthood administereth the gospel and holdeth the key of the mysteries of the kingdom, even the key of the knowledge of God.
20 Therefore, in the ordinances thereof, the power of godliness is manifest.
21 And without the ordinances thereof, and the authority of the priesthood, the power of godliness is not manifest unto men in the flesh;
Doctrine and Covenants 107:20 The power and authority of the lesser, or Aaronic Priesthood, is to hold the keys of the ministering of angels, and to administer in outward ordinances, the letter of the gospel, the baptism of repentance for the remission of sins, agreeable to the covenants and commandments.
I don't know how much plainer anyone could need it.
