"Moses was greatly troubled because his people were so wanting in faith, especially as they had repeatedly witnessed the manifestations of the power of God in their favor. He felt grieved that they should charge upon him the dangers and difficulties of their position, when he had simply followed the express commands of God. But he was strong in the faith that the Lord would bring them into safety; and he met and quieted the reproaches and fears of his people, even before he could himself discern the plan of their deliverance. 4T 22.4"
"And Moses said unto the people, Fear ye not, stand still, and see the salvation of the Lord, which he will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever."
The EGW passage describes Moses's faith and reassurance to the people, which directly relates to the sentiment expressed in Exodus 14:13.
