Except for verse 9c, verses 7-9 are exactly the same as 60.6-8.

In verse 7a Revised Standard Version has has promised, whereas it translates the same Hebrew text in 60.6a as “has spoken.” The translation should be the same in both passages.

In verse 9c the Hebrew has “I will shout over Philistia”; in 60.8 the Hebrew text is “Philistia will shout over me.” (Hebrew Old Testament Text Project does not consider this difference between the two passages.) Good News Translation reflects the difference between the two passages, while Revised Standard Version has the same translation for the two.
