Exodus 15:22-27; 16
The Israelites have been the recipients of the miracles and wonders of the Living God. The God of Abraham, Isaac and Jacob used His power to fulfill his promises to Abraham. The initial promises that God gave to Abraham in Genesis 12:2 are now a reality: to “make you (Abraham’s seed) into a great nation”. At this point, Moses is leading the people toward Mount Sinai. Moses had the assurance from God at the burning bush that he would return to that place with the Israelites. Exodus 3:12 says “And God said, ‘I will be with you. And this will be the sign to you that it is I who have sent you. When you have brought the people out of Egypt, you will worship God on this mountain.’”
The people have been saved from the bondage of slavery and have rejoiced, but they are now in the wilderness. All is not perfect, and the people start to murmur and complain.
