'Gall' in the Bible

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

therefore thus says Yahweh of Armies, the God of Israel, Behold, I will feed them, even this people, with wormwood, and give them water of gall to drink.

Therefore thus says Yahweh of Armies concerning the prophets: Behold, I will feed them with wormwood, and make them drink the water of gall; for from the prophets of Jerusalem is ungodliness gone forth into all the land.
