There are a few necessary assumptions to consider before you reach an understanding of the text.
1. The Bible is not a collection of disparate texts.
2. The author is God and his intent is constant.
3. The intent is spread over the different passages.
To understand the Bible we must be alert.
The message of the passage we just read is that we must choose between God and self.
The choice is not between God, mammon and Baal.
How do we reach this understanding?
The clue is in this text:
Deuteronomy 11:NET BibleFor the land where you are headed is not like the land of Egypt from which you came, a land where you planted seed and which you irrigated by hand like a vegetable garden.
Don't forget that the land God is giving Israel is the same land he pushed them out of when he sent a special dream to Joseph.
Why did God do this?
The life that Jacob and his family led was like the life of any other nomadic group. They constantly searched for the grazing for their flock which meant following the rain.
Contrast this with Egypt where people used the river to grow food.
This is then is the situation:
Egypt depend on themselves (own hands) for food.
Israel depended on God for food.
This results in different outlooks on life, world views:
Egypt prays to different gods for wealth, fertility, victory in warfare, etc. In other words, life is an existence that must be passed through with as little pain as possible, and the way to do this is to serve the different needs, do everything possible, including create gods, to build up a stock that would last for this life and also the afterlife, in the event there was an after life. I mentioned the creation of gods because that is the reality: they make a god, they decide on appropriate rites and they perform the rites for that god in order to achieve a result. The god serves them, not the other way around. If at all anything is being served, being indulged, it is their own needs. Covetousness, selfishness, is idolatry, serving the flesh.
The result of being in a situation where provision for life is in the hands of God is different. Whereas in Egypt fields were dug and watered by hand, here the land bears fruit only at the will of God. Now the availability of grain and grazing for men and animals is limited. The only way men could change the situation would be to adopt a nomadic lifestyle, like Jacob and his children, Joseph and his brothers. However, unlike the birds that fly south or the wildebeests that follow the rain and settle into a migration cycle, Israel cannot do the same without risking war, since the land has filled up with other tribes since the time of Jacob. God pushed Israel out of a dependence on self, by cyclic migration, to dependence on Him alone.
So really the choice is between depending on God or depending on your job:
Luke 12:22And He said to His disciples, “For this reason I say to you, do not worry about your life, as to what you will eat; nor for your body, as to what you will put on. 23“For life is more than food, and the body more than clothing. 24“Consider the ravens, for they neither sow nor reap; they have no storeroom nor barn, and yet God feeds them; how much more valuable you are than the birds! 25“And which of you by worrying can add a single hour to his life’s span? 26“If then you cannot do even a very little thing, why do you worry about other matters? 27“Consider the lilies, how they grow: they neither toil nor spin; but I tell you, not even Solomon in all his glory clothed himself like one of these. 28“But if God so clothes the grass in the field, which is alive today and tomorrow is thrown into the furnace, how much more will He clothe you? You men of little faith! 29“And do not seek what you will eat and what you will drink, and do not keep worrying. 30“For all these things the nations of the world eagerly seek; but your Father knows that you need these things. 31“But seek His kingdom, and these things will be added to you. 32“Do not be afraid, little flock, for your Father has chosen gladly to give you the kingdom.
