Matthew 16:19

19 I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."

Matthew 16:19 In-Context

17 And Jesus answered him, "Blessed are you, Simon son of Jonah! For flesh and blood has not revealed this to you, but my Father in heaven.
18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of Hades will not prevail against it.
19 I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven."
20 Then he sternly ordered the disciples not to tell anyone that he was the Messiah.
21 From that time on, Jesus began to show his disciples that he must go to Jerusalem and undergo great suffering at the hands of the elders and chief priests and scribes, and be killed, and on the third day be raised.
