'Disputed' in the Bible

Then some from what is called the Freedmen’s Synagogue, composed of both Cyrenians and Alexandrians, and some from Cilicia and Asia, came forward and disputed with Stephen.

And he spake boldly in the name of the Lord Jesus, and disputed against the Grecians: but they went about to slay him.

Therefore disputed he in the synagogue with the Jews, and with the devout persons, and in the market daily with them that met with him.

I found out that the accusations were about disputed matters in their law, and that there was no charge that merited death or chains.
