The Holy Spirit and God's power are spoken of as if they are something that can be poured out onto a person. (See: [[rc://en/ta/man/jit/figs-metaphor]])
The word "all" is a generalization. Alternate translation: "those who were oppressed by the devil" or "many people who were oppressed by the devil" (See: [[rc://en/ta/man/jit/figs-hyperbole]])
