'Bitter' in the Bible

So then, listen to what I, the Lord God of Israel who rules over all, say. 'I will make these people eat the bitter food of suffering and drink the poison water of judgment.

So then I, the Lord who rules over all, have something to say concerning the prophets of Jerusalem: 'I will make these prophets eat the bitter food of suffering and drink the poison water of judgment. For the prophets of Jerusalem are the reason that ungodliness has spread throughout the land.'"

The Lord says, "A sound is heard in Ramah, a sound of crying in bitter grief. It is the sound of Rachel weeping for her children and refusing to be comforted, because her children are gone."
