²¹ For there is a man whose labor is with wisdom, and with knowledge, and with ^[a]skilfulness; yet to a man that hath not labored therein shall he ^[b]leave it for his portion. This also is vanity and a great evil. ²² For what hath a man of all his labor, and of the ^[c]striving of his heart, wherein he laboreth under the sun? ²³ For all his days are but sorrows, and his travail is grief; yea, even in the night his heart taketh no rest. This also is vanity.
