Matthew 26:31

The Prediction of Peter’s Denial

26:31 Then Jesus said to them, “This night you will all fall away because of me, for it is written:

‘I will strike the shepherd,

and the sheep of the flock will be scattered.’ ⁴ 

¹ tn Grk “a certain man.” The Greek word ἄνθρωπος (anqrwpo") is used here in a somewhat generic sense.

² sn This individual with a hundred sheep is a shepherd of modest means, as flocks often had up to two hundred head of sheep.

³ sn Look for the one that went astray. The parable pictures God’s pursuit of the sinner. On the image of Jesus as the Good Shepherd, see John 10:1-18.
