﴿ وَٱتْرُكِ ٱلْبَحْرَ رَهْوًا ۖ إِنَّهُمْ جُندٌۭ مُّغْرَقُونَ ﴾

“and leave the sea becalmed [between thee and Pharaoh’s men]: for, verily, they are a host destined to be drowned!””

(And leave the sea behind at rest) spacious roads, spacious enough for Moses and his folk to pass through them, (for lo! they are a drowned host) Pharaoh and his folk will be drowned in the sea.
