To cook.

And utter a parable unto the rebellious house, and say unto them, Thus saith the Lord GOD; Set on a pot, set it on, and also pour water into it: gather the pieces thereof into it, even every good piece, the thigh, and the shoulder; fill it with the choice bones. Take the choice of the flock, and burn also the bones under it, and make it boil well, and let them SEETHE the bones of it therein. (Ezekiel 24:3-5 )
