line one's pockets, to

To accept bribes, or acquire money in some other questionable way. One writer claims that this term originated when a court tailor who wanted the patronage of Beau Brummel gave him a gift of a coat lined with banknotes. However, the term to line one’s purse, meaning to cram it full of gold or money, predates the eighteenth-century dandy by some two hundred years; Shakespeare used it in Othello (1.1), where Iago speaks of dishonest servants who “have lin’d their coats.”
