'Loins' in the Bible

'And thou, thou dost gird up thy loins, and hast arisen, and spoken unto them all that I command thee: be not affrighted because of them, lest I affright thee before them.

Thus said Jehovah unto me, 'Go, and thou hast got for thee a girdle of linen, and hast placed it on thy loins, and into water thou dost not cause it to enter:'

and I get the girdle, according to the word of Jehovah, and I place it on my loins.

Take the girdle that thou hast got, that is on thy loins, and rise, go to Phrat, and hide it there in a hole of the rock;

For, as the girdle cleaveth unto the loins of a man, So I caused to cleave unto Me The whole house of Israel, And the whole house of Judah, an affirmation of Jehovah, To be to Me for a people, and for a name, And for praise, and for beauty, And they have not hearkened.

Ask, I pray you, and see, is a male bringing forth? Wherefore have I seen every man, His hands on his loins, as a travailing woman, And all faces have been turned to paleness?

For every head is bald, and every beard diminished, On all hands cuttings, and on the loins -- sackcloth.
