WEB_Strongs(i)
  20 H5437 Therefore I began H2976 to cause H3820 my heart H2976 to despair H5999 concerning all the labor H5999 in which I had labored H8121 under the sun.
  21 H3426 For there is H120 a man H5999 whose labor H2451 is with wisdom, H1847 with knowledge, H5998 and with skillfulness; H5414 yet he shall leave H2506 it for his portion H120 to a man H5998 who has not labored H1892 for it. This also is vanity H7227 and a great H7451 evil.
  22 H1933 For what has H120 a man H5999 of all his labor, H7475 and of the striving H3820 of his heart, H1931 in which H6001 he labors H8121 under the sun?
  23 H3117 For all his days H4341 are sorrows, H6045 and his travail H3708 is grief; H3915 yes, even in the night H3820 his heart H7901 takes no rest. H1892 This also is vanity.
