Isaiah continues speaking.

He saw that there was no man, and was appalled that there was no one to intervene.

"Yahweh was appalled that no one came to help those who were suffering." or "Yahweh was astonished that no one came to help those who were suffering."

Therefore his own arm brought salvation for him

Yahweh's "arm" represents his ability and power. Alternate translation: "Yahweh used his own power to save the people" (See: rc://en/ta/man/jit/figs-metonymy)

his righteousness sustained him

"Righteousness" here is a quality that acts like a person. The word can be translated as an adjective. Alternate translation: "he did right as he always would do" (See: rc://en/ta/man/jit/figs-personification and rc://en/ta/man/jit/figs-abstractnouns)
