'Beings' in the Bible

And [the] human beings and [the] animals must be covered [with] sackcloth! And they must call forcefully to God, and each must turn from his evil way and from the violence that is in his hands.

So why shouldn't I be concerned about Nineveh, that great city, in which there are more than 120,000 human beings who do not know their right hand from their left, as well as a lot of livestock?
