'Yourself' in the Bible

Tell it not in Gath,Weep not at all.At Beth-le-aphrah roll yourself in the dust.

Make yourself bald and cut off your hair,Because of the children of your delight;Extend your baldness like the eagle,For they will go from you into exile.

“You will sow but you will not reap.You will tread the olive but will not anoint yourself with oil;And the grapes, but you will not drink wine.
