'Gall' in the Bible

Why do we sit still? Assemble yourselves, and let us enter into the fenced cities, and let us be silent there: for Jehovah our God hath put us to silence, and given us water of gall to drink, because we have sinned against Jehovah.

therefore thus saith Jehovah of hosts, the God of Israel, Behold, I will feed this people with wormwood, and give them water of gall to drink,

Therefore thus saith Jehovah of hosts concerning the prophets: Behold, I will feed them with wormwood, and make them drink water of gall; for from the prophets of Jerusalem is profaneness gone forth into all the land.
