'What is Man' in the Bible

What is man, that you have made him great, and that your attention is fixed on him,

What is man, that he may be clean? and how may the son of woman be upright?

What is man, that you keep him in mind? the son of man, that you take him into account?

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

There are words without number for increasing what is to no purpose, but what is man profited by them?

But a certain writer has given his witness, saying, What is man, that you keep him in mind? what is the son of man, that you take him into account?

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?
