'Mortal' in the Bible

I will make mortal man scarcer than pure goldAnd mankind than the gold of Ophir.

In the day thy plant thou causest to become great, And in the morning thy seed makest to flourish, A heap is the harvest in a day of overflowing, And of mortal pain.

"Then Assyria will fall by a sword that is not from human beings only a sword not wielded by mortal beings will devour them. They will flee from the sword, and their young men will be put to forced labor.

Your nakedness will be exposed, and your disgrace will also be seen. I'll take vengeance, and I will spare no mortal.

"I, I am the one who consoles you. Why are you afraid of mortal men, of mere human beings who are as short-lived as grass?
