'Sinews' in the Bible

Thou hast clothed me with skin and flesh, and hast fenced me with bones and sinews.

My bones are pierced in me in the night season: and my sinews take no rest.

“See now, his strength is in his loinsAnd his power is in the muscles and sinews of his belly.

He moveth his tail like a cedar: the sinews of his stones are wrapped together.
