'Poisoned' in the Bible

Why are we sitting still?Assemble yourselves, and let us go into the fortified citiesAnd let us perish there,Because the Lord our God has doomed usAnd given us poisoned water to drink,For we have sinned against the Lord.

therefore thus says the Lord of hosts, the God of Israel, “behold, I will feed them, this people, with wormwood and give them poisoned water to drink.
