Ezekiel 24:9-10

The Lord pronounced woe on the bloody city of Jerusalem and promised to make the pile of bones of the slain inhabitants great (cf. Isaiah 30:33). Therefore Ezekiel was to kindle a strong fire, to boil the meat well, to mix in the spices normally used when meat was cooked this way, and to let the bones burn. All this symbolized the fierceness of the attack on Jerusalem and the many people that would die there.
