'What is Man' in the Bible

What is man, that thou shouldest magnify him, And that thou shouldest set thy mind upon him,

What is man, that he should be clean? And he that is born of a woman, that he should be righteous?

What is man, that thou art mindful of him? and the son of man, that thou visitest him?

The Lord is on my side; I will have no fear: what is man able to do to me?

Jehovah, what is man, that thou takest knowledge of him? Or the son of man, that thou makest account of him?

Seeing there are many things that increase vanity, what is man the better?

But one in a certain place testified, saying, What is man, that thou art mindful of him? or the son of man, that thou visitest him?

So that we say with a good heart, The Lord is my helper; I will have no fear: what is man able to do to me?
