Moses stayed on the mountain with God for 40 days and 40 nights. He ate no food and drank no water. Not once, but this visit to the mountain for 40 days and nights without food and drink was done twice! What confirmation of how God can miraculously take care of the physical needs. Should we even think about doubting that He can take care of us?

Again God gives this admonition. It is such an easy thing to do, just teach the children... and look at the promise at the end if we do!
Deut 11:18-21
Fix these words of mine in your hearts and minds; tie them as symbols on your hands and bind them on your foreheads. Teach them to your children, talking about them when you sit at home and when you walk along the road, when you lie down and when you get up. Write them on the doorframes of your houses and on your gates, so that your days and the days of your children may be many in the land that the LORD swore to give your forefathers, as many as the days that the heavens are above the earth.

God told the Hebrew people He would give them every place they set their foot.
Deut 11:24-25
Every place where you set your foot will be yours: Your territory will extend from the desert to Lebanon, and from the Euphrates River to the western sea. No man will be able to stand against you. The LORD your God, as he promised you, will put the terror and fear of you on the whole land, wherever you go.
This area is much larger than the area of Israel today. God promised them that He would give them all the land where they would set their foot. Way back to Abraham, God told him to walk the land and He would give him every place he set his foot. God makes the same offer again...If only...

Interestingly, the boundaries of the present day Israel are the boundaries of the battle of Armageddon.

Again the people are given a warning for them to not fall into the trap of worshiping other gods in the land. How does that apply to us today? Do we worship other gods? What form do these gods take? Anything that replaces God in our lives is an idol. That can take many forms.
