nourish a viper in (one's) bosom(redirected from they have nourished a viper in their bosoms)
nourish a viper in (one's) bosom
To befriend, look after, or take care of someone who proves to be traitorous, untrustworthy, deceitful, or ungrateful. I thought the profligate had seen the light and was seeking redemption, and so I took him into my care. But before long, I knew I had nourished a viper in my bosom, as I awoke one morning to find myself robbed blind! I thought our love was not only mutual but indestructible; and yet, I have nourished a viper in my bosom all these years: my darling husband has cast me out and run off with a younger woman.

viper in one's bosom, (nourish) a
An ungrateful and treacherous friend; an individual whom one has helped and who returns the favor with treachery. This term comes from Aesop’s fable about a peasant who brings indoors a snake dying from the cold and is fatally bitten as soon as the snake recovers. Chaucer was among the first of the many writers to use this metaphor, which also made its way into the proverb collections of John Ray (1670), James Kelly (1721), and Thomas Fuller (1732). The term is variously put as snake or viper.
