'Cunning' 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.

But I am afraid that, even as the serpent beguiled Eve by his cunning, your minds may be corrupted and led away from the simplicity of [your sincere and] pure devotion to Christ.
