Pseudo-Jerome
Catena Aurea · Markusevangelium 14
And when they had sung an hymn, they went out into the mount of Olives. And Jesus saith unto them, All ye shall be offended because of me this night: for it is written, I will smite the shepherd, and the sheep shall be scattered. But after that I am risen, I will go before you into Galilee. But Peter said unto him, Although all shall be offended, yet will not I. And Jesus saith unto him, Verily I say unto thee, That this day, even in this night, before the cock crow twice, thou shalt deny me thrice. But he spake the more vehemently, If I should die with thee, I will not deny thee in any wise. Likewise also said they all.
In which the true resurrection is promised, that their hope may not be extinguished. There follows: But Peter said unto him, Although all shall be offended, yet will not I. Lo, a bird unfledged strives to raise itself on high; but the body weighs down the soul, so that the fear of the Lord is overcome by the fear of human death.
