Translation:

People may have to be specified, e.g. ‘those who-had-been-told’ (Javanese), ‘those dwelling there,’ ‘the inhabitants.’

If a break in the series of clauses is desirable, they came is best taken with what precedes, e.g. ‘people went out to see … and came to Jesus (or, to where Jesus was). There they found….’

And found the man … sitting …, or, ‘and there they came upon the man … and saw him (or, saw how he was) sitting…,’ ‘and there they perceived the man…; he was sitting….’ Cf. also on 7.10.

The man from whom the demons had gone, i.e. the man who was no longer demon possessed, the final result of what is told in vv. 29, 33.

Sitting at the feet of Jesus. The verb, suggesting an attitude of calm repose, contrasts with “driven” in v. 29. Where a literal rendering of the prepositional phrase would be misleading or unidiomatic it may be rendered, ‘(on the ground) before J.,’ ‘near J.,’ ‘beside J.’ (Zarma, Tboli), ‘in the presence (lit. at the nose) of J.’ (Ekari). If the language possesses an idiom said of a disciple who sits listening attentively to his master its use should be considered here. — This and the following phrases may have to be rendered as separate clauses.

Clothed contrasts with “had worn no clothes” in v. 27.

In his right mind is rendered variously, e.g. ‘come to his cleanness/purity’ (Marathi), ‘(his) thoughts having become right’ (Ekari), ‘his intelligence having-become clean again’ (Sranan Tongo), ‘having-mind’ (Batak Toba), ‘settled his mind’ (Tae’), or simply, ‘settled/fixed’ (Balinese).
