1 Corinthians 11:28
But let a man prove himself, and thus eat of the bread, and drink of the cup.
And see if there be any grievous way in me; and lead me in the way everlasting.
Search me, O God, and know my heart; prove me, and know my thoughts;
How many are mine iniquities and sins? Make me to know my transgression and my sin.
Prove me, Jehovah, and test me; try my reins and my heart:
2 Corinthians 13:5
examine your own selves if ye be in the faith; prove your own selves: do ye not recognise yourselves, that Jesus Christ is in you, unless indeed ye be reprobates?
The heart is deceitful above all things, and incurable; who can know it?
Be moved with anger, and sin not; meditate in your own hearts upon your bed, and be still. Selah.
I remember my song in the night; I muse in mine own heart, and my spirit maketh diligent search.
Search me, O God, and know my heart; prove me, and know my thoughts; And see if there be any grievous way in me; and lead me in the way everlasting.
I have thought on my ways, and turned my feet unto thy testimonies.
but let each prove his own work, and then he will have his boast in what belongs to himself alone, and not in what belongs to another.
