pluck up

Let none associate with the soul-destroying Manicheans, who by decoctions of chaff counterfeit the sad look of fasting, who speak evil of the Creator of meats, and greedily devour the daintiest, who teach that the man who plucks up this or that herb is changed into it. For if he who crops herbs or any vegetable is changed into the same, into how many will husbandmen and the tribe of gardeners be changed?
