Catena Aurea · Matthäusevangelium 26
And when they had sung an hymn, they went out into the mount of Olives. Then saith Jesus unto them, All ye shall be offended because of me this night; for it is written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad. But after I am risen again, I will go before you into Galilee. Peter answered and said unto him, Though all men shall be offended because of thee, yet will I never be offended. Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice. Peter said unto him, Though I should die with thee, yet will I not deny thee. Likewise also said all the disciples.
This hymn may be that thanksgiving which in John, (c. 17.) Our Lord offers up to the Father, when He lifted up His eyes and prayed for His disciples, and those who should believe through their word. This is that of which the Psalm speaks, The poor shall eat and be filled, they shall praise the Lord.] (Ps. 22:26.)
