'Festering' in the Bible

it's a festering skin disease in his body. The priest is to declare him unclean. The man need not be confined, since he's already unclean.

"The LORD will afflict you with the boils of Egypt, with tumors, skin disease, and festering rashes, and none of them will be curable.

From the sole of your foot to the top of your head, there's no soundness evident only bruises, sores, and festering wounds that haven't been cleaned out, bandaged, or treated with oil."
