“And they took their journey from Succoth, and encamped in Etham, in the edge of the wilderness. And the Lord went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night: He took not away the pillar of the cloud by day, nor the pillar of fire by night, from before the people.” SR 121.1
The Lord knew that the Philistines would oppose their passing through their land. They would say of them, They have stolen away from their masters in Egypt, and would make war with them. Thus God, by bringing them by way of the sea, revealed Himself a compassionate God as well as a God of judgment. The Lord informed Moses that Pharaoh would pursue them, and He directed him just where to encamp before the sea. He told Moses that He would be honored before Pharaoh and all his host. SR 121.2
After the Hebrews had been gone from Egypt some days, the Egyptians told Pharaoh that they had fled and would never return to serve him again. And they mourned because they had permitted them to leave Egypt. It was a very great loss for them to be deprived of their services, and they regretted that they had consented to let them go. Notwithstanding all they had suffered from the judgments of God, they were so hardened by their continual rebellion that they decided to pursue the children of Israel and bring them back by force unto Egypt. The king took a very large army and six hundred chariots, and pursued after them, and overtook them while encamped by the sea. SR 121.3
“And when Pharaoh drew nigh, the children of Israel lifted up their eyes, and, behold, the Egyptians marched after them; and they were sore afraid: and the children of Israel cried out unto the Lord. And they said unto Moses, Because there were no graves in Egypt, hast thou taken us away to die in the wilderness? wherefore hast thou dealt thus with us, to carry us forth out of Egypt? Is not this the word that we did tell thee in Egypt, saying, Let us alone, that we may serve the Egyptians? For it had been better for us to serve the Egyptians, than that we should die in the wilderness. And Moses said unto the people, Fear ye not, stand still, and see the salvation of the Lord, which He will shew to you today: for the Egyptians whom ye have seen today, ye shall see them again no more for ever. The Lord shall fight for you, and ye shall hold your peace.” SR 121.4
How soon the Israelites distrusted God! They had witnessed all His judgments upon Egypt to compel the king to let Israel go, but when their confidence in God was tested, they murmured, notwithstanding they had seen such evidences of His power in their wonderful deliverance. Instead of trusting in God in their necessity, they murmured at faithful Moses, reminding him of their words of unbelief which they uttered in Egypt. They accused him of being the cause of all their distress. He encouraged them to trust in God and withhold their expressions of unbelief, and they should see what the Lord would do for them. Moses earnestly cried to the Lord to deliver His chosen people. SR 122.1
