'Navel' in the Bible

Lo now, his strength is in his loins, and his force is in the navel of his belly.

It shall be health to thy navel, and marrow to thy bones.

Thy navel is like a round goblet, which wanteth not liquor: thy belly is like an 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 to supple thee; thou wast not salted at all, nor swaddled at all.
