Chapter 13 talks about the practices the Israelites needed to do in remembrance of what God did for them and for them to pass it on to their kids. If we don't teach the next generation the goodness of the Lord we are doing an injustice to God and them.
I think it's awesome that the wishes of Joesph having his bones taken out the Egypt were fulfilled. He had faith in God's promised land for the Israelites. Passing on Joesph's wishes was a sign of the peoples hope and faith that God would fill the promise also.
Pillar of cloud during the day and a pillar of fire at night had to be an amazing site to see. The pillar never departed from the people. It was a physical representation of the fact that God will never leave or forsake you!
If He puts you in a situation you can believe He has an exit strategy already planned out. Just like with putting the Israelites in Egypt there was a plan for them coming out of it. Trust in the fact that He sees all from the beginning to the end and that He is a good God that wants the best for you!
