'Thyself' in the Bible

Lo, this -- we searched it out -- it is right, hearken; And thou, know for thyself!

And it riseth -- as a lion Thou huntest me. And Thou turnest back -- Thou shewest Thyself wonderful in me.

Acquaint thyself, I pray thee, with Him, And be at peace, Thereby thine increase is good.

For then on the Mighty thou delightest thyself, And dost lift up unto God thy face,

If thou art able -- answer me, Set in array before me -- station thyself.

For a man like thyself is thy wickedness, And for a son of man thy righteousness.
