'Harm' in the Bible

Then I heard something like a voice among the four living creatures say, “A quart of wheat for a denarius, and three quarts of barley for a denarius—but do not harm the olive oil and the wine.”

Then I saw another angel, who had the seal of the living God rise up from the east. He cried out in a loud voice to the four angels who were empowered to harm the earth and the sea:

“Don’t harm the earth or the sea or the trees until we seal the slaves of our God on their foreheads.”

They were told not to harm the grass of the earth, or any green plant, or any tree, but only people who do not have God’s seal on their foreheads.

and they had tails with stingers like scorpions, so that with their tails they had the power to harm people for five months.

If anyone wants to harm them, fire comes from their mouths and consumes their enemies; if anyone wants to harm them, he must be killed in this way.
