Acts 13:23 → 2 Samuel 7:12

Acts 13:23's declaration — "From the descendants of this man, God has brought to Israel the Savior Jesus, as He promised" — grounds the claim directly in the Davidic covenant of 2 Sam 7:12, where God promises Nathan: "I will raise up your offspring [zar'akha] after you, who will come from your body, and I will establish his kingdom." The word "promised" (kat' epangelian) points to a covenant promise, and 2 Sam 7:12 is the foundational text. Paul's argument moves from David's election (13:22) to his offspring (13:23) to resurrection from the dead (13:33-37) as the fulfillment of the covenant promise that the Davidic son would have an eternal kingdom — a kingdom that could only be eternal if the Davidic son transcended death. The escalation over Solomon is explicit: Solomon's kingdom ended, but Jesus' resurrection establishes the eternal Davidic rule promised in 2 Sam 7:13, 16.
