Exodus 13:17-19

17When Pharaoh let the people go away, God did not lead them through the country of the Philistines. This was a short way for them to go, but God did not lead them that way. God said, ‘If the people have to fight a war, they may change their minds. Then they may return to Egypt.’

18So God led the people round by the desert road. They went towards the Red Sea. When the Israelites came out of the country of Egypt, they were ready to fight.

19Moses took Joseph's bones with him. Joseph had made the Israelites promise to do this. He had said, ‘One day, God will come and he will save you. Then you must carry my bones with you when you leave this place.’
