Deuteronomy 8:15-18

15He led you through the great and terrible wilderness—fiery serpents and scorpions, and thirsty ground where there was no water. He brought forth water for you from the flinty rock.

16He fed you in the wilderness with manna that your fathers did not know, in order to afflict you and test you, to do you good in the end.

17You may say in your heart, ‘My power and the might of my hand has made me this wealth.’

18Rather you are to remember Adonai your God, for it is He who gives you power to make wealth, in order to establish His covenant that He swore to your fathers—as it is this day.
