KJV:
I have seen the travail, which God hath given to the sons of men to be exercised in it.
NASB:
I have seen the task which God has given the sons of men with which to occupy themselves.
KJV:
I said in mine heart concerning the estate of the sons of men, that God might manifest them, and that they might see that they themselves are beasts.
NASB:
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."
KJV:
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; so that a man hath no preeminence above a beast: for all is vanity.
NASB:
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.
KJV:
There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.
NASB:
There was a certain man without a dependent, having neither a son nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, "And for whom am I laboring and depriving myself of pleasure?" This too is vanity and it is a grievous task.
KJV:
But those riches perish by evil travail: and he begetteth a son, and there is nothing in his hand.
NASB:
When those riches were lost through a bad investment and he had fathered a son, then there was nothing to support him.
KJV:
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.
NASB:
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.
KJV:
This is an evil among all things that are 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.
NASB:
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.
KJV:
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; so are the sons of men snared in an evil time, when it falleth suddenly upon them.
NASB:
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.
