Ecclesiastes 2:21

For there is a man whose labour is in wisdom, and in knowledge, and in equity ,.... Who does all he does, in natural, civil, and religious things, in the state, in his family, and the world, and whatsoever business he is engaged, in the wisest and best manner, with the utmost honesty and integrity, according to all the rules of wisdom and knowledge, and of justice and equity; meaning himself; the Midrash interprets this of God;

yet to a man that hath not laboured therein shall he leave it for his portion ; to his son, heir, and successor; who never took any pains, or joined with him, in acquiring the least part of it; and yet all comes into his hands, as his possession and inheritance: the Targum interprets this of a man that dies without children; and so others F26 R. Joseph Titatzak in loc. understand it of his leaving his substance to strangers, and not to his children.

This also is vanity, and a great evil ; not anything sinful and criminal, but vexatious and distressing.
