Prosperity comes from Jehovah.
A Song of Ascents; of Solomon.

1 Except Jehovah build the house,
They labor in vain that build it:
Except Jehovah keep the city,
The watchman waketh but in vain.
2 It is vain for you to rise up early,
To take rest late,
To eat the bread of toil;
For so he giveth unto his beloved sleep.
3 Lo, children are a heritage of Jehovah;
And the fruit of the womb is his reward.
4 As arrows in the hand of a mighty man,
So are the children of youth.
5 Happy is the man that hath his quiver full of them:
They shall not be put to shame,
When they speak with their enemies in the gate.
