the captives will be taken away from the warrior, and booty will be rescued

the ruthless

This nominal adjective refers to any ruthless person, not to one particular ruthless person. See how you translated this in Isaiah 49:24. Alternate translation: "ruthless people" (See: rc://en/ta/man/jit/figs-nominaladj)

I will ... save your children
