'Sons of Men' in the Bible

And I applied my heart to seek and to search out by wisdom concerning all that is done under heaven: it is a sore travail that God hath given to the sons of men to be exercised therewith.

I searched in my heart how to cheer my flesh with wine, my heart yet guiding me with wisdom, and how to lay hold on folly, till I might see what it was good for the sons of men that they should do under heaven all the days of their life.

I gathered me also silver and gold, and the treasure of kings and of the provinces; I gat me men-singers and women-singers, and the delights of the sons of men, musical instruments, and that of all sorts.

I have seen the travail which God hath given to the sons of men to be exercised therewith.

I said in my heart, It is because of the sons of men, that God may prove them, and that they may see that they themselves are but as beasts.

For that which befalleth the sons of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other; yea, they have all one breath; and man hath no preeminence above the beasts: for all is vanity.

Because sentence against an evil work is not executed speedily, therefore the heart of the sons of men is fully set in them to do evil.

This is an evil in all that is done under the sun, that there is one event unto all: yea also, the heart of the sons of men is full of evil, and madness is in their heart while they live, and after that they go to the dead.

For man also knoweth not his time: as the fishes that are taken in an evil net, and as the birds that are caught in the snare, even so are the sons of men snared in an evil time, when it falleth suddenly upon them.
