Heap on wood, kindle the fire,.... This is said either to the prophet, to do this in an emblematic way; or to the Chaldean army, to prepare for the siege, encompass the city, begin their attacks, and throw in their stones out of their slings and engines, and arrows from their bows:
consume the flesh; not entirely, since it is afterwards to be spiced; but thoroughly boil it; denoting the severe sufferings the inhabitants should undergo before their utter ruin:
spice it well; pepper them off; batter their walls, beat down their houses, distress them by all manner of ways and means; signifying that this would be grateful to the Lord, as his justice would be glorified in the destruction of this people; and as the plunder of them would be like a spiced and sweet morsel to the enemy; whose appetites would hereby be sharpened and become keen, and to whom the sacking and plundering the city would be as agreeable as well seasoned meat to a hungry man:
and let the bones be burnt; either under it, or rather in it; even the strongest and most powerful among the people destroyed, who should hold out the longest in the siege. The Targum of the whole is,
"multiply kings; gather an army; order the auxiliaries, and prepare against her warriors, and let her mighty ones be confounded.''
