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: 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: 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.
