The gloom will be dispelled from her who was in anguish

Isaiah speaks of people who are spiritually lost as if they were walking around in total darkness. This can be stated in active form. AT: "Yahweh will remove the darkness from her who was in anguish" (See: rc://en/ta/man/translate/figs-metaphor and rc://en/ta/man/translate/figs-activepassive)

The gloom

This word means "partial or total darkness." Translate as you translated "gloom" in Isaiah 08:22.
