Jesus Cures the Blind
Church of Sant'Apollinare Nuovo, Ravenna
There are several cures of the blind in the gospels, but only Matthew writes of Jesus healing two blind men in the same episode, in each case touching their eyes to heal them (9:27-31 and 20:30-33).
In the mosaic Jesus' healing hand is in the "Old Believers" configuration seen in many of the other panels.
