'Sons' in the Bible

And I set my mind to seek and explore by wisdom concerning all that has been done under heaven. It is a grievous task which God has given to the sons of men to be afflicted with.

I explored with my mind how to stimulate my body with wine while my mind was guiding me wisely, and how to take hold of folly, until I could see what good there is for the sons of men to do under heaven the few years of their lives.

I have seen the task which God has given the sons of men with which to occupy themselves.

I said to myself concerning the sons of men, “God has surely tested them in order for them to see that they are but beasts.”

For the fate of the sons of men and the fate of beasts is the same. As one dies so dies the other; indeed, they all have the same breath and there is no advantage for man over beast, for all is vanity.

Because the sentence against an evil deed is not executed quickly, therefore the hearts of the sons of men among them are given fully to do evil.

This is an evil in all that is done under the sun, that there is one fate for all men. Furthermore, the hearts of the sons of men are full of evil and insanity is in their hearts throughout their lives. Afterwards they go to the dead.

Moreover, man does not know his time: like fish caught in a treacherous net and birds trapped in a snare, so the sons of men are ensnared at an evil time when it suddenly falls on them.
