Remigius of Auxerre
Catena Aurea · Matthäusevangelium 27
And they crucified him, and parted his garments, casting lots: that it might be fulfilled which was spoken by the prophet, They parted my garments among them, and upon my vesture did they cast lots. And sitting down they watched him there; And set up over his head his accusation written, THIS IS JESUS THE KING OF THE JEWS. Then were there two thieves crucified with him, one on the right hand, and another on the left.
(ap. Gloss. ord.) Or, by the two thieves are denoted all those who strive after the continence of a strict life. They who do this with a single intention of pleasing God, are denoted by him who was crucified on the right hand; they who do it out of desire of human praise or any less worthy motive, are signified by him who was crucified on the left.
