Jeremiah 9:15

Because the people were stubborn, the Lord promised to feed them with wormwood (instead of honey), and to give them poisoned water ("gall" AV, instead of milk) to drink (cf. Jeremiah 8:14; Jeremiah 23:15; Deuteronomy 29:18; Matthew 27:34). "Wormwood" was a plant with a very bitter taste.
