For this our heart is faint,.... Our spirits sink; we are ready to swoon and die away; either for this, that we have sinned; because of our sins, they are so many, so great, and so aggravated; or for those distresses and calamities they have brought upon us before mentioned; or for the desolation of Zion, more especially, after expressed; and so the Targum,
"for this house of the sanctuary, which is desolate, our heart is weak:''
for these [things] our eyes are dim; or "darkened" b almost blinded with weeping; can scarcely see out of them; or as persons in a swoon; for dimness of sight usually attends faintness of spirit.
