'Proof' in the Bible

And he said, "You shall take the seven ewe-lambs from my hand {as proof on my behalf} that I dug this well."

because he has set a day on which he is going to judge the world in righteousness by the man who he has appointed, having provided proof to everyone [by] raising him from the dead."

And with this confidence, I was wanting to come to you previously, in order that you may have a second proof of my goodwill,

Therefore show to them the proof of your love and our boasting about you {openly before} the churches.

since you are demanding proof that Christ, who [is] not weak toward you, but is powerful among you, is speaking in me.

a proof of the righteous judgment of God, so that you may be considered worthy of the kingdom of God, on behalf of which also you are suffering,

Now faith is the realization of what is hoped for, the proof of things not seen.
