Adam Clarke on Ezekiel 24:5

Make it boil well - Let it boil over, that its own scum may augment the fire, that the bones - the soldiers, may be seethed therein. Let its contentions, divided counsels, and disunion be the means of increasing its miseries, רתח רתחיה rattach rethacheyha, let it bubble its bubbling; something like that of the poet: - "Bubble, bubble, toil and trouble:

Fire burn, and cauldron bubble."

Very like the noise made by ebullition, when a pot of thick broth, "sleek and slab," is set over a fierce fire. Such was that here represented in which all the flesh, the fat and the bones were to be boiled, and generally dissolved together.
