'Wherewith' in the Bible

What profit hath man of all his labour wherewith he laboureth under the sun?

And I hated all my labour wherewith I had been toiling under the sun, because I should leave it unto the man that shall be after me.

Then I went about to cause my heart to despair of all the labour wherewith I had laboured under the sun.

For what will man have of all his labour and of the striving of his heart, wherewith he hath wearied himself under the sun?

Behold what I have seen good and comely: it is to eat and to drink, and to enjoy good in all his labour wherewith man laboureth under the sun, all the days of his life which God hath given him: for that is his portion.
