'Thyself' in the Bible

Let them be for thyself alone, And not for strangers with thee.

Do this now, my son, and deliver thyself, Seeing thou art come into the hand of thy neighbor: Go, humble thyself, and importune thy neighbor;

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

If thou art wise, thou art wise for thyself; And if thou scoffest, thou alone shalt bear it.

Weary not thyself to be rich; Cease from thine own wisdom.

Fret not thyself because of evil-doers; Neither be thou envious at the wicked:

Put not thyself forward in the presence of the king, And stand not in the place of great men:

Boast not thyself of tomorrow; 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 thy hand upon thy mouth.
