We have a collection of 2 Jealousy quotes from Saint Augustine
"He that is jealous is not in love." (ID 8118)
"What I needed most was to love and to be loved, eager to be caught. Happily I wrapped those painful bonds around me; and sure enough, I would be lashed with the red-hot pokers or jealousy, by suspicions and fear, by burst of anger and quarrels." (ID 8165)
