68 But he denied it. "I don't know or understand what you're talking about," he said, and went out into the entryway.[1] 69 When the servant girl saw him there, she said again to those standing around, "This fellow is one of them." 70 Again he denied it. After a little while, those standing near said to Peter, "Surely you are one of them, for you are a Galilean." 71 He began to call down curses, and he swore to them, "I don't know this man you're talking about." 72 Immediately the rooster crowed the second time.[2] Then Peter remembered the word Jesus had spoken to him: "Before the rooster crows twice[3]you will disown me three times." And he broke down and wept.

Commentary on Mark 14:66-72

(Read Mark 14:66-72)

Peter's denying Christ began by keeping at a distance from him. Those that are shy of godliness, are far in the way to deny Christ. Those who think it dangerous to be in company with Christ's disciples, because thence they may be drawn in to suffer for him, will find it much more dangerous to be in company with his enemies, because there they may be drawn in to sin against him. When Christ was admired and flocked after, Peter readily owned him; but will own no relation to him now he is deserted and despised. Yet observe, Peter's repentance was very speedy. Let him that thinketh he standeth take heed lest he fall; and let him that has fallen think of these things, and of his own offences, and return to the Lord with weeping and supplication, seeking forgiveness, and to be raised up by the Holy Spirit.
