Bartimaeus, Shout!

Then they came to Jericho. As Jesus and his disciples, together with a large crowd, were leaving the city, a blind man, Bartimaeus (that is, the Son of Timaeus), was sitting by the roadside begging. When he heard that it was Jesus of Nazareth, he began to shout, "Jesus, Son of David, have mercy on me!" Many rebuked him and told him to be quiet, but he shouted all the more, "Son of David, have mercy on me!"

Mark 10:46-48

The Master nears:
Cry aloud, in your blindness,
Raise your voice still louder...
Shout through your darkness.
Shout, Shout, Shout!

Don't be silent, though they grumble.
Refuse the rebuke;
Ignore their propriety:
Yell and call, shriek and holler!
Beg light from the Son of David.

And plead for us,
the lame, the mute, and the blind,
too weak to rise,
too frail to ascend,
too darkened to find our way,
Lying on the roadside.

Call, "Mercy" upon these poor.
Rise and go, the Master calls.
