Lukas 17:13

17:13 raised their voices and said, “Jesus, Master, have mercy ¹  on us.”

Lukas 18:38

18:38 So ²  he called out, ³  “Jesus, Son of David, ⁴  have mercy ⁵  on me!”

[17:13]  ¹ sn “Have mercy on us” is a request to heal them (Luke 18:38-39; 16:24; Matt 9:27; 15:22; 17:15; 20:31-32; Mark 10:47-49).

[18:38]  ² tn Here καί (kai) has been translated as “so” to indicate the implied result of the blind man learning that Jesus was nearby.

[18:38]  ³ tn Grk “called out, saying.” The participle λέγων (legwn) is redundant in contemporary English and has not been translated.

[18:38]  ⁴ sn Jesus was more than a Nazarene to this blind person, who saw quite well that Jesus was Son of David. He understood what Luke 7:22-23 affirms. There was a tradition in Judaism that the Son of David (Solomon) had great powers of healing (Josephus, Ant. 8.2.5 [8.42-49]).

[18:38]  ⁵ sn Have mercy on me is a request for healing (cf. 17:13). It is not owed the man. He simply asks for God’s kind grace.
