William Burkitt on Acts 14:1

Here we have an account of the fourth journey which Paul and Barnabas undertook in their travels, to plant and propagate the Christian faith, and that was to Iconium.

Where observe, 1. The unity of these two great apostles, both amongst themselves and in the work of God: They went both together into the synagogue.

O how happy is it for the ministers of Christ to walk and work together in unity! to go hand in hand together in the service of the gospel, and with united endeavours promote the glory of God, and the interest of souls!

Observe, 2. As their unity, so their great constancy in performing their duty, notwithstanding all their persecutors' fury and obstinacy. Though the unbelieving Jews stirred up the Gentiles against the apostles, yet they continue preaching in the synagogues.

Observe, 3. The great success with which it pleased God to crown the endeavours of the holy apostles: a great multitude of both Jews and Gentiles believed; and that which doth constantly attend the success of the ministry of the word, namely, the envy and opposition of wicked men: they exasperated, or made the Gentiles' minds evil-affected against the brethren.
