'Disputing' in the Bible

But there arose certain of them that were of the synagogue called the synagogue of the Libertines, and of the Cyrenians, and of the Alexandrians, and of them of Cilicia and Asia, disputing with Stephen.

and neither in the temple did they find me disputing with any man or stirring up a crowd, nor in the synagogues, nor in the city.

And when he had said these words, the Jews departed, having much disputing among themselves.
