Matthew 16:18 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].
