(18) And many that believed.--More accurately, many of those that had believed. The word is probably used, as in Acts 19:2, for the whole process of conversion, including baptism, confession in this instance following on that rite, instead of preceding it. The words do not definitely state whether the confession was made privately to St. Paul and the other teachers, or publicly in the presence of the congregation; but the latter is, as in the confession made to the Baptist, much the more probable. (See Note on Matthew 3:6.) The feeling of a vague awe at this contact with the Unseen in some, the special belief in Christ as the Judge of all men in others, roused conscience into intense activity; the sins of their past lives came back upon their memories, and it was a relief to throw off the burden by confessing them.

Verse 18. - Many also of them that had believed for and many that believed, A.V.; confessing and declaring for and confessed and showed, A.V. Many also of them that had believed. This and the following verse speak of that class of converts who had previously been addicted to magic arts. It gives us a curious view of the extent to which magic prevailed among the Jews at this time. Nor was it less prevalent in heathen Ephesus. The magic formulae of Ephesus were famous under the name of Ἐφέσια γράμματα (see Renan, pp. 344,345, note), and the belief in magic seems to have been universal. Hesychius gives as the names of the oldest Ephesian charms, Aski, Kataski, Lix, Petrax, Damnameneus, AEsion, which he explains as meaning severally "Darkness, Light," "the Earth," "the Year," "the Truth" (Lewin, p. 334).

19:13-20 It was common, especially among the Jews, for persons to profess or to try to cast out evil spirits. If we resist the devil by faith in Christ, he will flee from us; but if we think to resist him by the using of Christ's name, or his works, as a spell or charm, Satan will prevail against us. Where there is true sorrow for sin, there will be free confession of sin to God in every prayer and to man whom we have offended, when the case requires it. Surely if the word of God prevailed among us, many lewd, infidel, and wicked books would be burned by their possessors. Will not these Ephesian converts rise up in judgement against professors, who traffic in such works for the sake of gain, or allow themselves to possess them? If we desire to be in earnest in the great work of salvation, every pursuit and enjoyment must be given up which hinders the effect of the gospel upon the mind, or loosens its hold upon the heart.And many that believed,.... In Jesus Christ, whose name was spoken of with great respect, and which spread fear in every person:

came; to the apostle:

and confessed; their sins; and acknowledged what a wicked life they had led:

and showed their deeds; their former evil deeds, which they had been guilty of; one copy reads, "their sins"; see Matthew 3:6.
