5, 6. And when Silas and Timotheus were come from Macedonia--that is, from Thessalonica, whither Silas had probably accompanied Timothy when sent back from Athens (see on Ac 17:15).
      Paul was pressed in the spirit--rather (according to what is certainly the true reading) "was pressed with the word"; expressing not only his zeal and assiduity in preaching it, but some inward pressure which at this time he experienced in the work (to convey which more clearly was probably the origin of the common reading). What that pressure was we happen to know, with singular minuteness and vividness of description, from the apostle himself, in his first Epistles to the Corinthians and Thessalonians (1Co 2:1-5; 1Th 3:1-10). He had come away from Athens, as he remained there, in a depressed and anxious state of mind, having there met, for the first time, with unwilling Gentile ears. He continued, apparently for some time, laboring alone in the synagogue of Corinth, full of deep and anxious solicitude for his Thessalonian converts. His early ministry at Corinth was colored by these feelings. Himself deeply humbled, his power as a preacher was more than ever felt to lie in demonstration of the Spirit. At length Silas and Timotheus arrived with exhilarating tidings of the faith and love of his Thessalonian children, and of their earnest longing again to see their father in Christ; bringing with them also, in token of their love and duty, a pecuniary contribution for the supply of his wants. This seems to have so lifted him as to put new life and vigor into his ministry. He now wrote his FIRST EPISTLE TO THE THESSALONIANS, in which the "pressure" which resulted from all this strikingly appears. (See Introduction to First Thessalonians). Such emotions are known only to the ministers of Christ, and, even of them, only to such as "travail in birth until Christ be formed in" their hearers.
