Exegesis:

Nazarēnos (1.24; 14.67; 16.6) ‘of Nazareth,’ ‘Nazarene.’

krazein (cf. 3.11) ‘to cry.’

huie Dauid (10.48; 12.35) ‘Son of David’: a messianic title.

eleēson (cf. 5.19) ‘have mercy,’ ‘be merciful.’

Translation:

It was … may require readjustment, e.g. ‘when he heard that Jesus of Nazareth was there.’

Cry out is in this context ‘shout.’

Son of David can usually be translated literally, since ‘son’ often permits expansion in the sense of anyone’s belonging to the lineage of such and such a person. However, in some languages an alternative term, roughly equivalent to our grandson may be necessary, so as to avoid a serious misunderstanding. On the other hand, there are often generic terms such as ‘offspring’ or ‘descendant,’ which can be used in such instances, if ‘son’ includes entirely too narrow a range of meaning.

For mercy see 5.19.
