'Sons of Men' in the Bible

I applied my heart to seek and to search out by wisdom concerning all that is done under the sky. It is a heavy burden that God has given to the sons of men to be afflicted with.

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

I also gathered silver and gold for myself, and the treasure of kings and of the provinces. I got myself male and female singers, and the delights of the sons of men -- musical instruments, and that of all sorts.

I have seen the burden which God has given to the sons of men to be afflicted with.

I said in my heart, "As for the sons of men, God tests them, so that they may see that they themselves are like animals.

For that which happens to the sons of men happens to animals. Even one thing happens to them. As the one dies, so the other dies. Yes, they have all one breath; and man has no advantage over the animals: 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 to all: yes 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 doesn't know his time. As the fish 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 falls suddenly on them.
