'Deal' in the Bible

But we have renounced the disgraceful things hidden because of shame; not walking in trickery or adulterating the word of God, but by stating the truth [openly and plainly], we commend ourselves to everyone’s conscience in the sight of God.

For though it is true that He was crucified through weakness, yet He now lives through the power of God. We also are weak, sharing His weakness, but with Him we shall be full of life to deal with you through the power of God.

For this cause I write these things while absent, that I may not when present deal sharply, according to the authority which the Lord gave me for building up, and not for casting down.
