'Thyself' in the Bible

In Gath tell ye not -- in Acco weep not, In Beth-Aphrah, in dust roll thyself.

Now gather thyself together, O daughter of troops, A siege he hath laid against us, With a rod they smite on the cheek the judge of Israel.

And I have cut off thy graven images, And thy standing-pillars out of thy midst, And thou dost not bow thyself any more To the work of thy hands.
