'Poison' in the Bible

Who was your guide through that great and cruel waste, where there were poison-snakes and scorpions and a dry land without water; who made water come out of the hard rock for you;

So that there may not be among you any man or woman or family or tribe whose heart is turned away from the Lord our God today, to go after other gods and give them worship; or any root among you whose fruit is poison and bitter sorrow;

They will be wasted from need of food, and overcome by burning heat and bitter destruction; and the teeth of beasts I will send on them, with the poison of the worms of the dust.

Their wine is the poison of dragons, the cruel poison of snakes.
