'Grievous' in the Bible

And I applied my heart to seek and search out by wisdom concerning all that is done under the heavens: this grievous occupation hath God given to the children of men to weary themselves therewith.

Therefore I hated life; because the work that is wrought under the sun is grievous unto me: for all is vanity and vexation of spirit.

Because all his days his task is painful and grievous; even at night his mind does not rest. This too is vanity.

There is one alone and without a second; also he hath neither son nor brother: yet is there no end of all his labour, neither is his eye satisfied with riches, and he saith not, For whom then am I labouring, and depriving my soul of good? This also is vanity and a grievous occupation.

There is a grievous evil that I have seen under the sun: riches kept for the owners thereof to their hurt;

And this also is a grievous evil, that in all points as he came so doth he go away, and what profit hath he, in having laboured for the wind?

a man to whom God gives wealth, riches, and honor, so that he lacks none of his heart's desires but God does not give him the capability to enjoy them. Instead, a stranger consumes them. This is pointless and a grievous affliction.
