'Proved' in the Bible

He successfully refuted the Jews in public and proved by the Scriptures that Jesus is the Messiah.

For if I have been doing some boasting about you to him, I have never been ashamed of it. Moreover, since everything we told you was true, our boasting to Titus has also proved to be true.

for the gospel we brought did not come to you in words only, but also with power, with the Holy Spirit, and with deep conviction. Indeed, you know what kind of people we proved to be while we were with you, acting on your behalf.
