'Unblameable' in the Bible

In the body of his flesh through death, to present you holy and unblameable and unreproveable in his sight:

To the end he may stablish your hearts unblameable in holiness before God, even our Father, at the coming of our Lord Jesus Christ with all his saints.

and let these also first be proved, then let them minister, being unblameable.

that thou keep the command unspotted, unblameable, till the manifestation of our Lord Jesus Christ,

wherefore, beloved, these things waiting for, be diligent, spotless and unblameable, by Him to be found in peace,
