'Thyself' in the Bible

Do this now, my son, and deliver thyself, when thou art come into the hand of thy friend; go, humble thyself, and make sure thy friend.

Deliver thyself as a roe from the hand of the hunter, and as a bird from the hand of the fowler.

If thou be wise, thou shalt be wise for thyself: but if thou scornest, thou alone shalt bear it.

Fret not thyself because of evil men, neither be thou envious at the wicked;

Prepare thy work without, and make it fit for thyself in the field; and afterwards build thine house.

Put not forth thyself in the presence of the king, and stand not in the place of great men:

Boast not thyself of to morrow; for thou knowest not what a day may bring forth.

If thou hast done foolishly in lifting up thyself, or if thou hast thought evil, lay thine hand upon thy mouth.
