Ecclesiastes 2:17–213 votes
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. Yea, I hated all my labour which I had taken under the sun: because I should leave it unto the man that shall be after me. And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity. Therefore I went about to cause my heart to despair of all the labour which I took under the sun. For there is a man whose labour is in wisdom, and in knowledge, and in equity; yet to a man that hath not laboured therein shall he leave it for his portion. This also is vanity and a great evil.
Ecclesiastes 4:7–83 votes
Then I returned, and I saw vanity under the sun. There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.
Luke 10:40–422 votes
But Martha was cumbered about much serving, and came to him, and said, Lord, dost thou not care that my sister hath left me to serve alone? bid her therefore that she help me. And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things: But one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her.
