To resist - That is, they were not able to "answer" his arguments.
The wisdom - This properly refers to his knowledge of the Scriptures; his skill in what "the Jews" esteemed to be wisdom - acquaintance with their sacred writings, opinions, etc.
And the spirit - This has been commonly understood of the Holy Spirit, by which he was aided; but it rather means the "energy, power," or "ardor" of Stephen. He "evinced" a spirit of zeal and sincerity which they could not withstand; which served, more than mere argument could have done, to convince them that he was right. The evidence of sincerity, honesty, and zeal in a public speaker will often go further to convince the great mass of mankind, than the most able argument if delivered in a cold and indifferent manner.
They there not able to resist the wisdom, etc. - He was wise, well exercised and experienced, in Divine things; and, as appears by his defense, in the following chapter, well versed in the Jewish history. The spirit by which he spake was the Holy Spirit, and its power was irresistible. They were obliged either to yield to its teachings, or were confounded by its truth. Several MSS. add to this verse, because he reproved them with boldness, they could not resist the truth. This reading is not genuine, though it exists (but in different forms) in some good MSS.
(8) And they were not able to resist the wisdom and the spirit by which he spake.
(8) False teachers, because they will not be overcome, flee from disputations and resort to manifest and open slandering and false accusations.
And they were not able to resist the wisdom,.... In Beza's most ancient copy, and in another manuscript it is added, "which was in him"; that divine wisdom, which the Spirit of wisdom gave him; they were not a match for him with respect to the knowledge of divine things; they could not answer the wise arguments he made use of, fetched out of the Scriptures of truth, in which he was well versed, and had a large knowledge of:
and the Spirit by which he spake; that is, the Holy Spirit, as the above exemplars of Beza, and the Ethiopic version read; the meaning is, they could not resist the Holy Spirit, by which Stephen spake, so as to overcome him, or put Stephen to silence, or confute him; otherwise they did resist him, or oppose themselves to him, but in vain, and without success; for they always resisted the Holy Ghost in Christ and in his apostles, as their fathers before them resisted him in the prophets, as Stephen observes to them, Acts 7:51 hereby was fulfilled what our Lord promised to his disciples, Matthew 10:19.
not able to resist the wisdom and the spirit by which he spake--What he said, and the power with which he spake it, were alike resistless.
They were not able to resist. They attempted to argue, but were silenced.
