'Loins' in the Bible

Thou therefore gird up thy loins, and arise, and speak unto them all that I command thee: be not dismayed at them, lest I dismay thee before them.

Thus saith Jehovah unto me, Go, and buy thee a linen girdle, and put it upon thy loins, and put it not in water.

So I bought a girdle according to the word of Jehovah, and put it upon my loins.

Take the girdle that thou hast bought, which is upon thy loins, and arise, go to the Euphrates, and hide it there in a cleft of the rock.

For as the girdle cleaveth to the loins of a man, so have I caused to cleave unto me the whole house of Israel and the whole house of Judah, saith Jehovah; that they may be unto me for a people, and for a name, and for a praise, and for a glory: but they would not hear.

Ask ye now, and see whether a man doth travail with child: wherefore do I see every man with his hands on his loins, as a woman in travail, and all faces are turned into paleness?

For every head is bald, and every beard clipped: upon all the hands are cuttings, and upon the loins sackcloth.
