'Deadly' in the Bible

Their wine [is] the poison of snakes, and [the] deadly poison of horned vipers.

So they sent and gathered all the rulers of [the] Philistines, and they said, "Send away the ark of the God of Israel and let it return to its place, so that it will not kill us and our people." For a {deadly confusion} was throughout all the city; the hand of God was very heavy there.

When I send my arrows of deadly famine against them, which will be as destruction that I will send [in order] to destroy you, I will increase famine against you, and I will break {the supply of food} for you.
