Ver. 11. And thou didst divide the sea before them] That which threatened to swallow them preserved them. "For this shall every one that is godly pray unto thee in a time when thou mayest be found: surely in the floods of great waters they shall not come nigh unto him," Psalms 32:6 .
As a stone into the mighty waters] As lead, Exodus 15:10. So shall Rome (that spiritual Egypt) once sink into the bottom of the sea, as a millstone thrust into it by a mighty angel, with a most impetuous force, Revelation 18:21 .
