'Injure' in the Bible

Then the five men went on and came to Laish and saw the people who were there, [how they were] living securely in the style of the Sidonians, quiet and peaceful; and there was no oppressive magistrate in the land humiliating them in anything, and they were far from the Sidonians and had no dealings with anyone.

They all conspired together to come and to fight against Jerusalem, and to cause a disturbance in it.

“When they persecute you in one city [because of your faith in Me], flee to the next; for I assure you and most solemnly say to you, you will not finish going through all the cities of Israel before the Son of Man comes.

Then I saw another angel coming up from the rising of the sun, holding the seal of the living God; and with a loud voice he called out to the four angels to whom it was granted [to have authority and power] to harm the earth and the sea,

They were told not to hurt the grass of the earth, nor any green thing, nor any tree, but [to hurt] only the people who do not have the seal (mark of ownership, protection) of God on their foreheads.

And if anyone wants to harm them, fire comes out of their mouth and devours their enemies; so if anyone wants to harm them, he must be killed in this way.
