'Harmful' in the Bible
I will grant peace in the land so that you will lie down to sleep without anyone terrifying you. I will remove harmful animals from the land, and no sword of war will pass through your land.
Someone went out to the field to gather some herbs and found a wild vine. He picked some of its fruit, enough to fill up the fold of his robe. He came back, cut it up, and threw the slices into the stew pot, not knowing they were harmful.
He said, "Get some flour." Then he threw it into the pot and said, "Now pour some out for the men so they may eat." There was no longer anything harmful in the pot.
See the one who is pregnant with wickedness, who conceives destructive plans, and gives birth to harmful lies --
His mouth is full of curses and deceptive, harmful words; his tongue injures and destroys.
Your own wickedness will bring about your punishment. Your unfaithful acts will bring down discipline on you. Know, then, and realize how utterly harmful it was for you to reject me, the Lord your God, to show no respect for me," says the Lord God who rules over all.
