Looking Back, Seeing Forward
Deuteronomy 8:2
And you shall remember the whole way that the LORD your God has led you these forty years in the wilderness, that he might humble you, testing you to know what was in your heart, whether you would keep his commandments or not. (ESV)
Joshua 3:3,4
...“As soon as you see the ark of the covenant of the LORD your God being carried by the Levitical priests, then you shall set out from your place and follow it. Yet there shall be a distance between you and it, about 2,000 cubits in length. Do not come near it, in order that you may know the way you shall go, for you have not passed this way before.” (ESV)
