'Explaining' in the Bible

explaining and demonstrating that it was necessary [for] the Christ to suffer and to rise from the dead, and [saying], "This Jesus whom I am proclaiming to you is the Christ."

And [when they] had set a day with him, many more came to him at his lodging place, to whom he was explaining from early in the morning until evening, testifying about the kingdom of God and attempting to convince them about Jesus from both the law of Moses and the prophets.
