John Trapp on Ezekiel 21:7

Ver. 7. For the tidings] Ol the Chaldaeans comming. This was to the wicked as thoſe knuckles of a mans hand were afterward to Baltaſar, to write them their deſtiny: or as Daniel was to him, to read it unto them. Whenas the righteous man is no whit afraid of evil tidings, his heart is fixed truſting in the Lord, Pſal. 112.7.

And every heart ſhall melt, &c.] As wax before the fire: which, before the danger, ſeemed to be made all of ſteel or adamant. The wicked, when in adverſity, are wofully deſpondent and creſt-falne: as was the King of Sodom, Gen. 14. Manaſſeh among the buſhes, 2 Chron. 33.12. and others not a few, who in their proſperity ſeem to face the heavens and to draw the devil himſelf to a duel.

And all hands ſhall be feeble] The ſpirits and blood being run to the heart, in that fright, to relieve it.

And all knees ſhall be weak as water] Heb. ſhall go into water, that is, they ſhall bepiſſe themſelves for fear, ſaith Jerom: they ſhall be all on a cold ſweat, ſay others, or their knees ſhall ſhake, inſtar aquae tremulae, and knock together as Belſhazzar's did, Dan. 5.6.
