'Humankind' in the Bible

So what if I sin? What have I done against you, you observer of humankind? Why have you made me your target? Why burden yourself with me?

"Surely you know that it has been from old, ever since humankind was placed on the earth,

all flesh would perish together, and humankind would return to dust.

which the clouds pour down and shower on humankind abundantly.
