Seeing there be many things that increase vanity, what is man the better? Ecclesiastes 6:11 (KJV)
‘More words… more vanity,’ highlights the transient nature of things. Vanity or ‘enigma’ here is translated as ‘fleeting.’ (Bartholomew, 204) Qoheleth seems to state that the vanity of labouring under the sun cannot be resolved by investing more labour into it. As Henry writes, “what residuum has he, what overplus, what real advantage, when he comes to balance his account?” Or in other words, what remains after much labour is only vanity.
