Jeremiah 33:6 - Ellicott's Commentary On The Whole Bible

Health and cure... — The first word is, as in Jeremiah 8:22; Jeremiah 30:17, the bandage, or “plaister,” which was prominent in the therapeutics of the East. It is possible that both words may have been spoken in direct contrast with the pestilence which was ravaging the city (Jeremiah 21:9; Jeremiah 27:13; Jeremiah 38:2). In any case, however, the words have a higher and figurative meaning. It was true of the city and its people that the “whole head was sick, and the whole heart faint” (Isaiah 1:5); and Jehovah promises to manifest Himself as the healer of that spiritual disease which was worse than any pestilence.
