Then Simon himself believed also: and when he was baptized, he continued with Philip, and wondered, beholding the miracles and signs which were done.

And Simon also himself believed: and being baptized, he continued with Philip; and beholding signs and great miracles wrought, he was amazed.

Then Simon himself believed also; and being baptized, he adhered to Philip. And being astonished, wondered to see the signs and exceeding great miracles which were done.

And Simon also himself believed; and, having been baptised, continued constantly with Philip; and, beholding the signs and great works of power which took place, was astonished.

and Simon also himself did believe, and, having been baptized, he was continuing with Philip, beholding also signs and mighty acts being done, he was amazed.

Simon himself also believed, and after being baptized remained in close attendance on Philip, and was full of amazement at seeing such signs and such great miracles performed.

And Simon himself had faith and, having had baptism, he went with Philip and, seeing the signs and the great wonders which he did, he was full of surprise.

Then Simon himself also believed and, when he had been baptized, he adhered to Philip. And now, seeing also the greatest signs and miracles being wrought, he was amazed and stupefied.

Even Simon believed, and after his baptism attached himself to Philip, and was in his turn mystified at seeing signs and great miracles constantly occurring.

Simon also himself. He which had besotted the whole city with his witchery receiveth the truth together with others. He which had boasted himself to be the principal power of God submitteth himself to God, [Christ; ] though he were brought to the knowledge of the gospel, not so much for his own sake alone, as for the whole country's sake, that that offense might be taken out of the way which might have hindered the unskillful. And to this end tendeth that which Luke setteth down afterward, that he wondered at the signs. For God meant to triumph over this man, whom the Samaritans counted a petit God; [1] which cometh to pass whilst he is enforced to give glory to the true miracles, after that his vain boasting is taken away. And yet he giveth not himself over sincerely to Christ; for then his ambition, and that wicked and profane account which he made of the gifts of God, should not break out. And yet I am not of their mind who think that he made only a semblance of faith, seeing he did not believe. Luke saith plainly that he believed, and the reason is added, Because he was touched with wondering. How, then, doth he shortly after betray himself to be but a hypocrite? I answer, That there is some mean between faith and mere dissimulation. The Epicures [Epicureans] and Lucianists do profess that they believe, whereas notwithstanding they laugh inwardly, whereas the hope of eternal life is unto them a vain thing; finally, whereas they have no more godliness than dogs or swine. But there be many who howsoever they be not regenerate with the Spirit of adoption, and do not addict themselves unto God with the true affection of the heart, being overcome with the power of the Word, do not only confess that that is true which is taught, but are also touched with some fear of God, so that they receive doctrine; for they conceive that God must be heard; that he is both the author and also the judge of the world. Therefore, they make no semblance of faith before men, which is none, but they think that they believe. And this faith continueth only for a time, whereof Christ speaketh in Mark, (Mark 4; Luke 8:13;) to wit, when the seed of the Word conceived in the mind is, notwithstanding, choked forthwith with divers cares of the world, or with wicked affections, so that it never cometh to any ripeness; yea, rather, it groweth out of kind unto unprofitable corn nothing worth. Such, therefore, was Simon's faith; he perceiveth that the doctrine of the gospel is true, and he is enforced to receive the same with the feeling of his conscience; but the groundwork is wanting; that is, the denial of himself. Whereupon it followed that his mind was enwrapped in dissimulation, which he uttereth forthwith. But let us know that his hypocrisy was such as he deceived himself in; and not that gross hypocrisy whereof Epicures and such like make boast; [2] because they dare not confess the contempt of God. He was baptized. It appeareth plainly, by this example of Simon that all men have not that grace given them in baptism, which grace is there figured. The opinion of the Papists is this, That unless mortal sin be the cause of let, [3] all men receive the truth and effect with the signs. So that they attribute unto the sacraments magical force, as if they did profit without faith, But let us know that the Lord offereth to us by the sacraments, whatsoever the annexed promises do sound; [4] and that they are not offered in vain, so that [5] being directed unto Christ by faith, we set [seek] from him whatsoever the sacraments do promise. And although the receiving of baptism did profit him nothing then, yet if conversion followed afterward, as some men suppose, the profit was not extinguished nor abolished. For it cometh to pass oftentimes that the Spirit of God worketh afterward after a long time, that the sacraments may begin to show forth their force. [6] Did cleave to Philip. Whereas Philip admitted him into his company, it appeareth thereby how hard a matter it is to know hypocrites. And this is a trial of our patience. So Demas was a companion of Paul for a time; afterward he became an unfaithful revolt [7] (2-Timothy 4:10,) Finally, we cannot escape this evil, but that wicked men and deceitful will sometimes join themselves unto us; and if at any time the wicked creep craftily into our company, proud censors burden us unjustly, as if we were to answer for their misdeeds. Though we must take heed of facility, which causeth the gospel to be slandered oftentimes, and we must be so much the more vigilant, that we admit none without great choice, forasmuch as we hear that great men have been deceived. He saith that he was made astonied with the greatness of the signs; that we may know that that great power, whereof he boasted, was nothing else but juggling and smokes. And Luke speaketh not in this place of any plain wondering, but of a damp or trance which causeth a man to forget what he doth. [8]

Then Simon himself believed also - That is, he believed that Jesus had performed miracles, and was raised from the dead, etc. All this he could believe in entire consistency with his own notions of the power of magic; and all that the connection requires us to suppose is that he believed this Jesus had the power of working miracles; and as he purposed to turn this to his own account, he was willing to profess himself to be his follower. It might have injured his popularity, moreover, if he had taken a stand in opposition when so many were professing to become Christians. People often profess religion because, if they do not, they fear that they will lose their influence, and be left with the ungodly. That Simon was not a real Christian is apparent from the whole narrative, Acts 8:18, Acts 8:21-23.
And when he was baptized - He was admitted to a "profession" of religion in the same way as others. Philip did not pretend to know the heart; and Simon was admitted because he "professed" his belief. This is all the evidence that ministers of the gospel can now have, and it is no wonder that they, as well Philip, are often deceived. The reasons which influenced Simon to make a profession of religion seem to have been these:
(1) An impression that Christianity was "true." He seems to have been convinced of this by the miracles of Philip.
(2) the fact that many others were becoming Christians; and "he" went in with the multitude. This is often the case in revivals of religion.
(3) he was willing to make use of Christianity to advance his own power, influence, and popularity - a thing which multitudes of men of the same mind with Simon Magus have been willing since to do.
He continued - It was customary and natural for the disciples to remain with their teachers. See Acts 2:42.
And wondered - This is the same word that is translated "bewitched" in Acts 8:9, Acts 8:11. It means that he was amazed that Philip could "really" perform so much greater miracles than "he" had even pretended to. Hypocrites will sometimes be greatly attentive to the external duties of religion, and will be greatly surprised at what is done by God for the salvation of sinners.
Miracles and signs - Greek: signs and great powers, or great miracles. That is, so much greater than he pretended to be able to perform.

Simon himself believed also - He was struck with the doctrine and miracles of Philip - he saw that these were real; he knew his own to be fictitious. He believed therefore that Jesus was the Messiah, and was in consequence baptized.
Continued with Philip, and wondered - ΕξιϚατο, He was as much astonished and confounded at the miracles of Philip as the people of Samaria were at his legerdemain. It is worthy of remark that εξιϚατο comes from the same root, εξιϚημι, as the word εξιϚων, in Acts 8:9, and, if our translation bewitched be proper there, it should be retained here; and then we should read, Then Simon himself believed and was baptized, and continued with Philip, being Bewitched, beholding the miracles and signs which were done. We may see, from this circumstance, how improper the term bewitched is, in the 9th and 11th verses.

(6) Then Simon himself believed also: and when he was baptized, he continued with Philip, and wondered, beholding the miracles and signs which were done.
(6) The wicked and the highly reprobate are often forced to taste the good gift of God, but they immediately spit it out again.

Then Simon himself believed also,.... With an historical and temporary faith, as that Jesus was the Messiah, &c. or at least he pretended, to believe this, and professed that he did believe, what others did, and Philip preached:
and when he was baptized; upon profession of his faith, which he so artfully made, that Philip could not discover his hypocrisy: but taking him to be a sincere believer, admitted him to baptism: after which,
he continued with Philip; kept close to him, and got into a familiar acquaintance with him; and constantly attended on his ministry, as if he had been a sincere disciple and follower of Christ:
and wondered, beholding the miracles and signs which were done; he was as much amazed at the miraculous performances of Philip, as the inhabitants of Samaria had been at his, which he could observe were real things; and this increased his wonder, and threw him into an ecstasy, that he was scarce himself: whereas he knew that what he did were only sham performances, and legerdemain tricks.

Then Simon himself believed also--Left without followers, he thinks it best to join the man who had fairly outstripped him, not without a touch of real conviction.
and . . . was baptized--What a light does this throw on what is called Baptismal Regeneration!
he continued with Philip--"was in constant attendance upon" him.

Then Simon himself believed also. There has been much needless discussion whether Simon was sincere. It would never have been doubted had we not been told that later he fell into sin. It is best to take the Scripture in its manifest sense. He became a believer like the rest. He was baptized like the rest; then, like many others, at a later period, under temptation, he fell into sin. It is impossible to believe that a man of his power and influence in Samaria would have yielded outwardly to the gospel and shown the deference he manifested to Philip unless he was at the time sincere. But he was of the class described by the Savior when the seed of the sower fell among among thorns.

And Simon believed - That is, was convinced of the truth.
