This is Daniel 9:1–27 from the Greek Septuagint, a canonical passage of Jewish apocalyptic literature set during the reign of Darius the Mede. The chapter opens with Daniel studying Jeremiah's prophecy about seventy years of Jerusalem's desolation, which prompts him to pray on behalf of Israel in fasting, sackcloth, and ashes. The prayer (vv. 4–19) is an extended communal confession: Daniel acknowledges Israel's persistent disobedience, refusal to heed the prophets, and the consequent divine judgment — exile and the ruin of Jerusalem — all framed as just punishment that God warned about through Moses. The passage's most distinctive and influential element is the angel Gabriel's response (vv. 20–27), which reinterprets Jeremiah's "seventy years" as "seventy weeks" (hebdomads) decreed over the people and the holy city — a timeframe structured as seven weeks, sixty-two weeks, and a final week — culminating in the anointing of a "holy of holies," the cutting off of an anointed one, the destruction of the city and sanctuary, and an "abomination of desolation." This seventy-weeks oracle became one of the most debated prophetic texts in Jewish and Christian tradition, variously read as referring to Antiochus IV Epiphanes, the Roman destruction of Jerusalem, or eschatological events.
