Ecclesiastes 9:9

Live joyfully with the wife whom thou lovest, the lawfully wedded spouse, all the days of the life of thy vanity, which He hath given thee under the sun, all the days of thy vanity, Proverbs 5:15; Proverbs 18:22; for that is thy portion in this life, and in thy labor which thou takest under the sun, that is, a proper enjoyment of God's blessings will compensate the believer for the toil and labor which is the inevitable lot of men in life.
