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:
Two are better than one; because they have a good reward for their labour.
NASB:
Two are better than one because they have a good return for their labor.
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:
Again, if two lie together, then they have heat: but how can one be warm alone?
NASB:
Furthermore, if two lie down together they keep warm, but how can one be warm alone?
KJV:
And if one prevail against him, two shall withstand him; and a threefold cord is not quickly broken.
NASB:
And if one can overpower him who is alone, two can resist him. A cord of three strands is not quickly torn apart.
