[2] According to the Gospel account in Matthew 9:27-31, as Jesus continues his journey after raising the daughter of Jairus, two blind men follow him, calling out, "Have mercy on us, Son of David!"
[3] The story is sometimes thought of as a loose adaptation of one in the Gospel of Mark, of the healing of a blind man called Bartimaeus, but in fact is a different story, The healing of Bartimaeus takes place near Jericho, involves two men who call out from the roadside as Jesus passes by, and comes later in Matthew 20:29-34.
The author of the Matthew Gospel introduces the term 'Son of David' to indicate that the healings show Jesus as the Messiah.
[4] This is confirmed by Cornelius a Lapide, where he comments on this passage, writing: These blind men had conceived the hope of recovering their sight from Christ from the many and great miracles which they had heard were done by Him.
We believe that Thou art the Son of David, that is, the Messiah, to whom this healing of blindness and other diseases has been promised by the Prophets.
