'Man' in the Bible

But someone testified somewhere, saying, "What is man, that you remember him, or the son of man, that you care for him?

But see how great this man [was], to whom Abraham the patriarch gave a tenth from the spoils!

a minister of the sanctuary and of the true tabernacle which the Lord set up, not man.

And therefore these were fathered from one man, and [he] being as good as dead, as the stars of heaven in number and like the innumerable sand by the shore of the sea.

So then, we can say with confidence, "The Lord [is] my helper, I will not be afraid. What will man do to me?"
