Congestion
The umbrella collects two passages where congestion — inflamed or thickened tissue, swelling under the skin — appears in scripture. One is a diagnostic rule for distinguishing a burn-scar from spreading disease; the other is a covenant-curse list naming the affliction among the punishments for disobedience.
The burn-scar diagnostic
In the priestly examination of skin lesions, a bright spot at the site of a burn must be watched. If after seven days "the bright spot remains in its place, and has not spread in the skin, but is dim; it is the rising of the burning, and the priest will pronounce him clean: for it is the scar of the burning" (Leviticus 13:28). The "rising of the burning" — localized congestion, raised but not advancing — is read as a healed scar rather than as an active plague. The protocol turns on whether the swelling is bounded or spreading.
A covenant-curse affliction
The Deuteronomic curse-list places inflammation among the bodily afflictions that pursue the disobedient: "[The Speech of] Yahweh will strike you with consumption, and with fever, and with inflammation, and with fiery heat, and with drought, and with blasting, and with mildew; and they will pursue you until you perish" (Deuteronomy 28:22). Congestion — fever and inflammation — sits in the same series with environmental blights (drought, blasting, mildew). The body and the land suffer together under the curse.
