nkjv@Ecclesiastes:2:19 @ And who knows whether he will be wise or a fool? Yet he will rule over all my labor in which I toiled and in which I have shown myself wise under the sun. This also is vanity.
nkjv@Ecclesiastes:2:20 @ Therefore I turned my heart and despaired of all the labor in which I had toiled under the sun.
nkjv@Ecclesiastes:2:21 @ For there is a man whose labor is with wisdom, knowledge, and skill; yet he must leave his heritage to a man who has not labored for it. This also is vanity and a great evil.
