And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the scriptures,

People's New Testament

17:2 Paul, as his manner was. It was his custom always to begin his work in the synagogue if he found one. Here he showed from the Old Testament that the promised Messiah should die, and rise again, that Jesus complied with these conditions, and hence must be the Christ. This line of argument was continued in the synagogue for three sabbaths. This indicates how long he continued to argue in the synagogue, not how long he remained here.

Wesley's Notes

17:2 And Paul, according to his custom - Of doing all things, as far as might be, in a regular manner, went in to them three Sabbath days - Not excluding the days between.

Jamieson-Fausset-Brown Bible Commentary

2-4. Paul, as his manner was-always to begin with the Jews.

went in unto them-In writing to the converts but a few months after this, he reminds them of the courage and superiority to indignity, for the Gospel's sake, which this required after the shameful treatment he had so lately experienced at Philippi (1Th 2:2).

Matthew Henry's Concise Commentary

17:1-9 The drift and scope of Paul's preaching and arguing, was to prove that Jesus is the Christ. He must needs suffer for us, because he could not otherwise purchase our redemption for us; and he must needs have risen again, because he could not otherwise apply the redemption to us. We are to preach concerning Jesus that he is Christ; therefore we may hope to be saved by him, and are bound to be ruled by him. The unbelieving Jews were angry, because the apostles preached to the Gentiles, that they might be saved. How strange it is, that men should grudge others the privileges they will not themselves accept! Neither rulers nor people need be troubled at the increase of real Christians, even though turbulent spirits should make religion the pretext for evil designs. Of such let us beware, from such let us withdraw, that we may show a desire to act aright in society, while we claim our right to worship God according to our consciences.
