And when Silas and Timotheus were come from Macedonia, Paul was pressed in the spirit, and testified to the Jews that Jesus was Christ. When Silas and Timotheus were come - We have seen, Acts 17:13, that when Paul was obliged to leave Berea, because of the persecution raised up against him in that place, he left Silas and Timotheus behind; to whom he afterwards sent word to rejoin him at Athens with all speed. It appears, from 1 Thessalonians 3:10, that, on Timothy's coming to Athens, Paul immediately sent him, and probably Silas with him, to comfort and establish the Church at Thessalonica. How long they labored here is uncertain, but they did not rejoin him till some time after he came to Corinth. It appears that he was greatly rejoiced at the account which Timothy brought of the Church at Thessalonica; and it must have been immediately after this that he wrote his first epistle to that Church, which is probably the first, in order of time, of all his epistles.
Paul was pressed in spirit - Συνειχετο τῳ πνευματι, or he was constrained by the Spirit of God, in an extraordinary manner, to testify to the Jews that Jesus was the Christ. Instead of τῳ πνευματι, in the spirit, τῳ λογῳ, in the word or doctrine, is the reading of ABDE, three others; both the Syriac, Coptic, Vulgate, Basil, Chrysostom, and others. Griesbach has received this reading into the text, and Bp. Pearce thus paraphrases the verse: "And when Silas and Timotheus were come from Macedonia, Paul set himself, together with them, wholly to the word; i.e. he was fully employed, now that he had their assistance, it preaching the Gospel, called the word in Acts 4:4; Acts 16:6, Acts 16:32; Acts 17:11. St. Luke seems to have intended to express here something relating to St. Paul which was the consequence of the coming of Silas and Timotheus; and that was rather labouring with them more abundantly in preaching the word than his being "pressed in spirit." This appears to be the true sense of the word, and that τῳ λογῳ is the genuine reading there can be no doubt. Συνειχετο, which we translate pressed, and which the Vulgate translates instabat, Bp. Pearce thinks should be translated una cum illis instabat, he earnestly strove together with them, τῳ λογῳ, in preaching the word. The true sense is given by Calmet, Paul s'employoit a precher encore avec plus d'ardeur, Paul was employed with more ardour in preaching, and testifying to the Jews that Jesus was the Christ. From this time we hear no more of Silas; probably he died in Macedonia.
