'Thyself' in the Bible

Declare ye it not at Gath, weep ye not at all: in the house of Aphrah roll thyself in the dust.

Now gather thyself in troops, O daughter of troops: he hath laid siege against us: they shall smite the judge of Israel with a rod upon the cheek.

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.
