17 Then Jesus answered him, Blessed (happy, fortunate, and to be envied) are you, Simon Bar-Jonah. For flesh and blood [men] have not revealed this to you, but My Father Who is in heaven.
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. [Isa. 22:22.]
20 Then He sternly and strictly charged and warned the disciples to tell no one that He was Jesus the Christ.
21 From that time forth Jesus began [clearly] to show His disciples that He must go to Jerusalem and suffer many things at the hands of the elders and the high priests and scribes, and be killed, and on the third day be raised from death.
22 Then Peter took Him aside to speak to Him privately and began to reprove and charge Him sharply, saying, God forbid, Lord! This must never happen to You!
23 But Jesus turned away from Peter and said to him, Get behind Me, Satan! You are in My way [an offense and a hindrance and a snare to Me]; for you are minding what partakes not of the nature and quality of God, but of men.
