Numbers 33

God had Moses recount their journey through the wilderness from the very beginning, when they left Egypt, to where they currently were – the Transjordan.  He prepares them for entering the land that he promised them, but not without a warning.
55:56 “But if you don’t drive out the inhabitants of the land before you, those you allow to remain will become barbs for your eyes and thorns for your sides; they will harass you in the land where you will live,  And what I had planned to do to them, I will do to you.”
What am I holding onto that is from the world and not from God?
