'Proved' in the Bible

James's relative Judas, and Judas Iscariot who proved to be a traitor.

If therefore you have not proved yourselves faithful in dealing with the wealth that is tainted with fraud, who will entrust to you the true good?

but as regards the holiness of His Spirit was decisively proved by His Resurrection to be the Son of God--I mean concerning Jesus Christ our Lord,

For what if some Jews have proved unfaithful? Shall their faithlessness render God's faithfulness worthless?

For if the message delivered through angels proved to be true, and every transgression and act of disobedience met with just retribution,

The sorrow comes in order that the testing of your faith--being more precious than that of gold, which perishes and yet is proved by fire--may be found to result in praise and glory and honour at the re-appearing of Jesus Christ.
