31 Then saith Jesus to them, All ye shall be offended in me during this night. For it is written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad. 32 But after that I shall be risen, I will go before you to Galilee. 33 And Peter answering said to him, If all shall be offended in thee, I will never be offended. 34 Jesus said to him, Verily I say to thee, that during this night, before [the] cock shall crow, thou shalt deny me thrice. 35 Peter says to him, If I should needs die with thee, I will in no wise deny thee. Likewise said all the disciples also.

Commentary on Matthew 26:31-35

(Read Matthew 26:31-35)

Improper self-confidence, like that of Peter, is the first step to a fall. There is a proneness in all of us to be over-confident. But those fall soonest and foulest, who are the most confident in themselves. Those are least safe, who think themselves most secure. Satan is active to lead such astray; they are most off their guard: God leaves them to themselves, to humble them.
