'Sons' in the Bible

And I have given my heart to seek and to search out by wisdom concerning all that hath been done under the heavens. It is a sad travail God hath given to the sons of man to be humbled by it.

I have sought in my heart to draw out with wine my appetite, (and my heart leading in wisdom), and to take hold on folly till that I see where is this -- the good to the sons of man of that which they do under the heavens, the number of the days of their lives.

I got men-servants, and maid-servants, and sons of the house were to me; also, I had much substance -- herd and flock -- above all who had been before me in Jerusalem.

I gathered for me also silver and gold, and the peculiar treasure of kings and of the provinces. I prepared for me men-singers and women-singers, and the luxuries of the sons of man -- a wife and wives.

I have seen the travail that God hath given to the sons of man to be humbled by it.

I said in my heart concerning the matter of the sons of man that God might cleanse them, so as to see that they themselves are beasts.

For an event is to the sons of man, and an event is to the beasts, even one event is to them; as the death of this, so is the death of that; and one spirit is to all, and the advantage of man above the beast is nothing, for the whole is vanity.

Who knoweth the spirit of the sons of man that is going up on high, and the spirit of the beast that is going down below to the earth?

Because sentence hath not been done on an evil work speedily, therefore the heart of the sons of man is full within them to do evil.

This is an evil among all that hath been done under the sun, that one event is to all, and also the heart of the sons of man is full of evil, and madness is in their heart during their life, and after it -- unto the dead.

For even man knoweth not his time; as fish that are taken hold of by an evil net, and as birds that are taken hold of by a snare, like these are the sons of man snared at an evil time, when it falleth upon them suddenly.
