Deuteronomy 8:1-3 Darby Translation (DARBY)
8 Every commandment which I command thee this day shall ye take heed to do, that ye may live, and multiply, and enter in and possess the land which Jehovah swore unto your fathers.
2 And thou shalt remember all the way which Jehovah thy God led thee these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thy heart, whether thou wouldest keep his commandments or not.
3 And he humbled thee, and suffered thee to hunger, and fed thee with the manna, which thou hadst not known, and which thy fathers knew not; that he might make thee know that man doth not live by bread alone, but by everything that goeth out of the mouth of Jehovah doth man live.
Deuteronomy 8:1-3 New International Version (NIV)
Do Not Forget the Lord
8 Be careful to follow every command I am giving you today, so that you may live and increase and may enter and possess the land the Lord promised on oath to your ancestors. 2 Remember how the Lord your God led you all the way in the wilderness these forty years, to humble and test you in order to know what was in your heart, whether or not you would keep his commands. 3 He humbled you, causing you to hunger and then feeding you with manna, which neither you nor your ancestors had known, to teach you that man does not live on bread alone but on every word that comes from the mouth of the Lord.
