Now at Iconium they entered together into the Jewish synagogue and spoke in such a way that a great number of both Jews and Greeks believed.
Acts 14:1 ESV

From the beginning of Paul's missionary journeys, he went to the Jewish synagogue in each town first. This was necessary because the Gospel must be preached to the Jews first and only then to the Gentiles.

Some justify their hatred of Jews because the Jews rejected Christ, but the Bible itself proves this to be false. The religious leadership mostly rejected Christ, but some of them didn't, and a great many of the Jewish laity believed.
