'Discussing' in the Bible

So he was discussing in the synagogue with the Jews and the God-fearing [Gentiles], and in the marketplace every day with those who happened to be there.

So he entered into the synagogue [and] was speaking boldly for three months, discussing and attempting to convince [them] concerning the kingdom of God.

But as he was discussing righteousness, self-control and the judgment to come, Felix became frightened and said, “Go away for the present, and when I find time I will summon you.”

Then Festus, [after] discussing [this] with [his] council, replied, "You have appealed to Caesar--to Caesar you will go!"
