'Navel' in the Bible

it shall be health for thy navel, and moisture for thy bones.

Thy navel is a round goblet, which wanteth not mixed wine; Thy belly a heap of wheat, set about with lilies;

And as for thy nativity, in the day thou wast born thy navel was not cut, neither wast thou washed in water for cleansing; thou wast not rubbed with salt at all, nor swaddled at all.
