Jeremiah 13:22 - Matthew Poole's English Annotations on the Holy Bible

Hypocrites will rarely confess their own shame and God's righteousness, but are ready to expostulate and dispute with God, and to call him to account why he hath dealt so with them, as if God had dealt unjustly. But (saith God) if thou shouldst have any such thoughts in thine heart, do but remember thine iniquities, how many and how great they have been, thy nakedness is discovered because of these, and for these thou art exposed to contempt and shame. Probably these phrases are fetched from the usual practice of soldiers, when they have conquered a place and taken prisoners, to strip them, and leave those of either sex, either no clothes to cover their nakedness, or nothing but their own rags, not sufficient to cover their nakedness. By skirts is meant the lower part of their bodies covered with the lower part of their garments.
