'Kill' in the Bible

I looked, and there was a pale green horse! Its rider's name was Death, and Hades followed him. They were given authority over one-fourth of the earth to kill people using wars, famines, plagues, and the wild animals of the earth.

They were not allowed to kill them, but were only allowed to torture them for five months. Their torture was like the pain of a scorpion when it stings someone.

So the four angels who were ready for that hour, day, month, and year were released to kill one-third of humanity.

When they have finished their testimony, the beast that comes up from the bottomless pit will wage war against them, conquer them, and kill them.
