John Trapp on Nehemiah 9:11

Verſe 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, Pſal. 32.6.

As a ſtone into the mighty waters] As lead, Exod. 15.10. So ſhall Rome (that ſpiritual Egypt) once ſinke into the bottome of the Sea, as a milſtone thruſt into it by a mighty Angel, with a moſt impetuous force, Rev. 18.21.
