'Kill' in the Bible

And another horse came out--a fiery-red one; and power was given to its rider to take peace from the earth, and to cause men to kill one another; and a great sword was given to him.

I looked and a pale-colored horse appeared. Its rider's name was Death, and Hades came close behind him; and authority was given to them over the fourth part of the earth, to kill with the sword or with famine or pestilence or by means of the wild beasts of the earth.

Their mission was not to kill, but to cause awful agony for five months; and this agony was like that which a scorpion inflicts when it stings a man.

And the four angels who had been kept in readiness for that hour, day, month, and year, were set at liberty, so that they might kill a third part of mankind.

"And when they have fully delivered their testimony, the Wild Beast which is to rise out of the bottomless pit will make war upon them and overcome them and kill them.
