To be at the "right hand of God" is a symbolic action of receiving great honor and authority from God. The phrase "having been exalted" can be stated in active form. AT: "having been exalted to the place of honor and authority beside God" or "having received honor and authority when God exalted him to the place beside him" (See: [[rc://en/ta/man/translate/translate-symaction]] and [[rc://en/ta/man/translate/figs-activepassive]])
Here the words "poured out" mean that Jesus, who is God, made these events to happen. It is implicit that he does this by giving the Holy Spirit to the believers. AT: "he has caused to happen these things that" (See: [[rc://en/ta/man/translate/figs-idiom]] and [[rc://en/ta/man/translate/figs-explicit]])
Here the words "pour out" mean to give generously and abundantly. See how you translated a similar phrase in [Acts 2:17](./16.md). AT: "given abundantly" (See: [[rc://en/ta/man/translate/figs-idiom]])
