'Own' in the Bible

He taketh the wise in their own craftiness; and the counsel of the wily is carried headlong:

If I justified myself, mine own mouth would condemn me; were I perfect, he would prove me perverse.

Then wouldest thou plunge me in the ditch, and mine own clothes would abhor me.

Behold, if he slay me, yet would I trust in him; but I will defend mine own ways before him.

Thine own mouth condemneth thee, and not I; and thy lips testify against thee.

The steps of his strength shall be straitened, and his own counsel shall cast him down.

For he is sent into the net by his own feet, and he walketh on the meshes;

Like his own dung doth he perish for ever; they which have seen him shall say, Where is he?

Neither have I gone back from the commandment of his lips; I have laid up the words of his mouth more than the purpose of my own heart.

And these three men ceased to answer Job, because he was righteous in his own eyes.
