Charles Ellicott Commentary Isaiah 54:9

"For this is [as] the waters of Noah unto me; for as I have sworn that the waters of Noah shall no more go over the earth, so have I sworn that I will not be wroth with thee, nor rebuke thee." — Isaiah 54:9 (ASV)

This is as the waters of Noah. — This observation is interesting for two main reasons:

1. It shows the writer’s knowledge of the book of Genesis .
2. It is one of the few references to the Deluge outside that book in the Old Testament.

Strictly speaking, Genesis 9:11 speaks of a “covenant,” not an “oath.” However, it would be idle to find a difficulty in the use of words which, as referring to a Divine act, are almost or altogether interchangeable.

It is obvious that these words have found their fulfilment not in any earthly city but in the heavenly Jerusalem.
