He told them, "All of you will be tempted to be afraid of Me this night, for it is written, I will smite the shepherd and the sheep will be scattered." This prophecy, cited from Zechariah (13:7), points out that the suffering of the Son is associated with the will of the Father, implying that the Jews, under divine permission, delivered Christ to crucifixion. The apostles are compared to sheep, innocent in nature. The Lord referred to this ancient prophecy so that the disciples would not misinterpret His words as a disapproval of them. To further comfort them, He proclaimed, "After My resurrection, I will go before you to Galilee," the site of one of His post-resurrection appearances (Matthew 28:16).
In response, Peter, displaying arrogance, asserted, "Even if all shall be tempted of You, I will never be tempted." Such self-assuredness led St. John Chrysostom to identify two faults in Peter’s statement: first, he contradicted the Lord, and second, he placed himself above the others, effectively a third fault in claiming self-sufficiency. To address Peter's pride, the Lord foretold his denial: "Amen, I say to you, that you will deny Me three times this night, before the rooster crows twice." This prediction came to pass with chilling accuracy. Yet, Peter, blinded by his overconfidence, insisted, "If I must die with You, I will not deny You." The other disciples, having not yet faced trial, expressed their own misguided fervor, pledging that they too would remain loyal to their Master in the face of danger, echoing Peter's promises even though they lacked the strength to uphold them.
