Musar sur Samuel 1 14:6

And a man who has a job or some occupation by which he supports his family should not think, "If not for this job I would be utterly lost." But he should trust in the Creator may He be Blessed, and think that if this work were not here to occupy him, then the Creator may He be Blessed, would provide his sustenance through some other means, because all the work of his hands and his needs are in the hands of God, and God has many messengers (of good fortune), as Scripture says : "For there is no restraint of the Lord to save by many or by few" (Samuel 14:6), and it says further : "It is He who gives power to get wealth" (Deut. 8:18), and it says : "Not by might nor by power but by My spirit says the Lord of Hosts" (Zech. 4:6).
