Isaías 53

Isaías 53:2
Therefore, Christ is both the great mountain and the small mountain: truly great because He is the great Lord and His power is great; small because it is written: You have made him a little lower than the angels. Wherefore also Isaiah says: We beheld Him, and He had no form nor comeliness. Nevertheless, He became less from great and greater from less. Less from great, because, when He was in the form of God, He emptied Himself and took the form of a servant; greater from less, because Daniel says: And the stone which was cut out of the mountain, became a great mountain and filled the whole earth. — Interrogation of Job and David, 2.4.17
Isaías 53:7
For this is the price of our liberty, as Peter says, ye were redeemed with the precious Blood, not indeed of a lamb, but of Him Who came as a lamb, in meekness and humility, and redeemed the whole world with the one offering of His Body, as He himself says, I was brought as a lamb to the slaughter. Wherefore John also says, Behold the Lamb of God, which taketh away the sin of the world. — Letter 75, 6
