'Mankind' in the Bible

The four angels were freed who had been prepared for that hour and day and month and year, so that they might kill one third of mankind.

By these three plagues were one third of mankind killed: by the fire, the smoke, and the sulfur, which proceeded out of their mouths.

The rest of mankind, who were not killed with these plagues, didn't repent of the works of their hands, that they wouldn't worship demons, and the idols of gold, and of silver, and of brass, and of stone, and of wood; which can neither see, nor hear, nor walk.
