This speaks about a promise as if it were something a person could look for and see. AT: "I am waiting expectantly for God to do what he promised our forefathers he would do" (See: [[rc://en/ta/man/translate/figs-metaphor]])
The phrase "our twelve tribes" stands for the people in those tribes. AT: "This is also what our fellow Jews in the twelve tribes were waiting for" (See: [[rc://en/ta/man/translate/figs-metonymy]])
Paul uses a question to challenge the Jews present. They believe God can raise the dead but do not think God brought Jesus back to life. This can be expressed as a statement. "Raises the dead" here is an idiom for "gives life to dead people." AT: "You do not think it is beyond reason that God can bring a dead person back to life, do you?" (See: [[rc://en/ta/man/translate/figs-rquestion]] and [[rc://en/ta/man/translate/figs-idiom]]).
