Then Aaron lifted his hands toward the people and blessed them. And having sacrificed the sin offering, the burnt offering and the fellowship offering, he stepped down.
The sons of Amram: Aaron and Moses. Aaron was set apart, he and his descendants forever, to consecrate the most holy things, to offer sacrifices before the Lord, to minister before him and to pronounce blessings in his name forever.
At that time the Lord set apart the tribe of Levi to carry the ark of the covenant of the Lord, to stand before the Lord to minister and to pronounce blessings in his name, as they still do today.
The Levitical priests shall step forward, for the Lord your God has chosen them to minister and to pronounce blessings in the name of the Lord and to decide all cases of dispute and assault.
Do not repay evil with evil or insult with insult. On the contrary, repay evil with blessing, because to this you were called so that you may inherit a blessing.
