Matthew 16:18-20

And I say to you that you are Peter, and on this rock I will build My church; and the gates of Hades (death) will not overpower it [by preventing the resurrection of the Christ]. [Eph 1:22; 4:15; 5:23; Col 1:18] I will give you the keys (authority) of the kingdom of heaven; and whatever you bind [forbid, declare to be improper and unlawful] on earth will have [already] been bound in heaven, and whatever you loose [permit, declare lawful] on earth will have [already] been loosed in heaven.” [Is 22:22; Matt 18:18] Then He gave the disciples strict orders to tell no one that He was the Christ (the Messiah, the Anointed).
