'Thyself' in the Bible

But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth.

But refuse profane and old wives' fables, and exercise thyself rather unto godliness.

Till I come, give thyself to reading, to exhortation, to teaching.

Meditate upon these things; give thyself wholly to them; that thy profiting may appear to all.

Take heed unto thyself, and unto the doctrine; continue in them: for in doing this thou shalt both save thyself, and them that hear thee.

Lay hands suddenly on no man, neither be partaker of other men's sins: keep thyself pure.

Perverse disputings of men of corrupt minds, and destitute of the truth, supposing that gain is godliness: from such withdraw thyself.
