Ezekiel 7:17

All hands shall be feeble ,.... No strength in them, to lay hold on weapons of war to defend themselves, or fight the enemy; no heart nor courage in them, to go forth and meet him; and even afraid to lift up their voice in mourning, lest they should be heard, and pursued, and taken:

and all knees shall be weak as water ; tremble and beat one against another, for fear of the enemy; or,

"shall flow with water,'

as the Targum; either with sweat or urine, which are sometimes both caused by fear.
