Isaiah continues speaking.

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

AT: “Yahweh was appaled 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

"Arm" is a metaphor for "power." AT: "Yahweh used his own power to save the people" (See: rc://en/ta/man/translate/figs-metonymy)

and his righteousness sustained him

God's nature is to always do what is just and right. AT: "and he did right as he always would do"
