18 And I tell you, you are Peter [Greek, Petros—a large piece of rock], and on this rock [Greek, petra—a huge rock like Gibraltar] I will build My church, and the gates of Hades (the powers of the infernal region) shall not overpower it [or be strong to its detriment or hold out against it].
19 I will give you the keys of the kingdom of heaven; and whatever you bind (declare to be improper and unlawful) on earth must be what is already bound in heaven; and whatever you loose (declare lawful) on earth must be what is already loosed in heaven.
Matthew 16:18-19 AMPC
