Matthew Poole and continuators on Ezekiel 21:31

31 And I will pour out mine indignation upon thee, I will blow against thee in the fire of my wrath, and deliver thee into the hand of brutish men, and skilful to destroy.

As a flood sweeps all away, so God will let out his indignation to overwhelm the Ammonites.

As those who melt down mettals blow upon the Mettal in the Fire, that the Fire might burn the fiercer, and consume the dross.

Or, as there is no hope to one delivered up to barbarous, merciless ruffians, whose Trade is to destroy, so will God deal with these Ammonites.

Marginal references: Or, burning.
