It is vain for you to rise up early, to stay up late, eating the bread of toil, for he gives sleep to his loved ones.
Context
1 Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain.
2 It is vain for you to rise up early, to sit up late, to eat the bread of sorrows: for so he giveth his beloved sleep.
3 Lo, children are an heritage of the LORD: and the fruit of the womb is his reward.
