Hastings' Dictionary of the Bible

Lucre The Eng. word ‘lucre’ is in AV [Note: Authorized Version.] always qualified by the adj. ‘filthy,’ because the word itself had not then the offensive meaning it has now. Erasmus speaks of God turning men’s wickedness ‘into the lucre and encreace of godlynesse.’ It simply meant gain. Filthy lucre means sordid gain.
