A prophet of priestly family
Jeremiah belonged to a priestly house of Anathoth, a town in the territory of Benjamin a short distance from Jerusalem. His father is named in the scriptural and synaxarion accounts as Helkiah (Hilkiah), a priest. This priestly background placed Jeremiah close to the worship of the Temple even as his message turned increasingly against the false confidence the people placed in the Temple while abandoning the covenant.
The Orthodox tradition reckons his life roughly six hundred years before the birth of Christ, in the seventh and sixth centuries BC. His ministry is associated with the reign of King Josiah of Judah and continued under Josiah's successors, spanning the turbulent final decades of the kingdom before its destruction.
The ministry and its sufferings
Jeremiah's preaching warned Judah that its idolatry and unfaithfulness would bring the judgment of subjugation to Babylon. To make the warning vivid, the tradition relates that he wore first a wooden yoke and then an iron one, carrying it among the people as a sign of the bondage to come. His message was deeply unpopular, and he endured mockery, beating, and imprisonment.
Among the trials recounted of him, the prophet's enemies cast him into a pit — described in the synaxarion as filled with mire and foul creatures — where he nearly perished. He was drawn out through the intervention of the God-fearing court official Habdemelek (the Ebed-Melech of Scripture), only to be confined again. When Nebuchadnezzar took Jerusalem, the prophet was released and remained near the ruined city in mourning.
Egypt, death, and later traditions
After the catastrophe, according to the tradition, Jeremiah was carried into Egypt by Jews who fled the Babylonians, settling at Tahpanhes, a place known in Greek as Daphnae. There, the synaxarion relates, he continued to prophesy and was at last put to death by stoning; the Church keeps his memory on the first of May.
Several traditions cluster around the prophet beyond the events of his life. One, drawing on the Second Book of Maccabees, holds that Jeremiah hid the Ark of the Covenant with the Tablets of the Law in a cave to preserve them from the invaders. Another tradition relates that, long after his death, his relics were transferred to Alexandria. The Books of Jeremiah and of Lamentations are ascribed to him in the scriptural and liturgical tradition.
