Acts 5:16

There came also a multitude out of the cities round about unto Jerusalem The best MSS. have no word for unto. The construction without that preposition would be and there came also together the multitude out of the cities round about Jerusalem. The use of the word city(πόλις) is common even when the places so called are very insignificant, as of Nazareth (Matthew 2:23), Nain (Luke 7:11), and Arimathæa (Luke 23:51).

bringing sick folks, and them which were vexed with unclean spirits It was recognized that the power of the Apostles extended not only to physical, but also to spiritual maladies. Indeed the whole history being of a supernatural character, the cures wrought on ordinary maladies were of the nature of signs and wonders, and spake of a power which was not human. The power here displayed is that which in Christ's own life was confessed to be that of the Son of God (Luke 4:40-41).

The verb in the original for vexedis found only here and in Luke 6:18 in the N. T., and like the word rendered "gave up the ghost" (Acts 5:5; Acts 5:10), is used frequently in the works of Greek medical writers, so that it is such a word as we should expect to find a physician using in the description of this malady.

unclean spirits are those which are called wickedin other parts of the New Testament (Matthew 12:45, &c.), and the former epithet is probably applied to them because the sufferer in his state of frenzy wandered into places where he would incur ceremonial defilement, as the demoniac who had his dwelling among the tombs (Mark 5:3), the latter on account of the evil effects so often patent in the condition of the afflicted person, as loss of speech, hearing and other senses, the belief of the Jews being that spirits afflicted with such maladies were the cause of the like affliction in human beings.

and they were healed every one For it was only a complete faith which had prompted the bringing them unto the Apostles, and to such faith all thingshad been promised by Christ (Mark 9:23).
