KJV: I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.
NASB: I said to myself, "Behold, I have magnified and increased wisdom more than all who were over Jerusalem before me; and my mind has observed a wealth of wisdom and knowledge."
KJV: I got me servants and maidens, and had servants born in my house; also I had great possessions of great and small cattle above all that were in Jerusalem before me:
NASB: I bought male and female slaves and I had homeborn slaves. Also I possessed flocks and herds larger than all who preceded me in Jerusalem.
KJV: For God giveth to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth travail, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.
NASB: For to a person who is good in His sight He has given wisdom and knowledge and joy, while to the sinner He has given the task of gathering and collecting so that he may give to one who is good in God's sight. This too is vanity and striving after wind.
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.
