Charles Ellicott Commentary Jeremiah 5:28

"They are waxed fat, they shine: yea, they overpass in deeds of wickedness; they plead not the cause, the cause of the fatherless, that they may prosper; and the right of the needy do they not judge." — Jeremiah 5:28 (ASV)

They overpass the deeds of the wicked.— Better (the English being ambiguous), they exceed in deeds (literally, words or things) of wickedness. The prophet dwells not only on the prosperity of the wicked, but on their callous indifference to the well-being of the poor.

Yet they prosper. —Better, so that they (the fatherless) may prosper. They do not judge with a view to that result. The words allow, however, in Hebrew as in English, for the sense that they (the wicked themselves) may prosper. That was all they aimed at or cared for.
