KJV:
For there is a man whose labour is in wisdom, and in knowledge, and in equity; yet to a man that hath not laboured therein shall he leave it for his portion. This also is vanity and a great evil.
NASB:
When there is a man who has labored with wisdom, knowledge and skill, then he gives his legacy to one who has not labored with them. This too is vanity and a great evil.
KJV:
Again, I considered all travail, and every right work, that for this a man is envied of his neighbour. This is also vanity and vexation of spirit.
NASB:
I have seen that every labor and every skill which is done is the result of rivalry between a man and his neighbor. This too is vanity and striving after wind.
