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:
For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up.
NASB:
For if either of them falls, the one will lift up his companion. But woe to the one who falls when there is not another to lift him up.
KJV:
There is no end of all the people, even of all that have been before them: they also that come after shall not rejoice in him. Surely this also is vanity and vexation of spirit.
NASB:
There is no end to all the people, to all who were before them, and even the ones who will come later will not be happy with him, for this too is vanity and striving after wind.
KJV:
When thou vowest a vow unto God, defer not to pay it; for he hath no pleasure in fools: pay that which thou hast vowed.
NASB:
When you make a vow to God, do not be late in paying it; for He takes no delight in fools. Pay what you vow!
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:
A man to whom God hath given riches, wealth, and honour, so that he wanteth nothing for his soul of all that he desireth, yet God giveth him not power to eat thereof, but a stranger eateth it: this is vanity, and it is an evil disease.
NASB:
a man to whom God has given riches and wealth and honor so that his soul lacks nothing of all that he desires; yet God has not empowered him to eat from them, for a foreigner enjoys them. This is vanity and a severe affliction.
