Chaldea

Chaldea is the biblical name for the southern Mesopotamian region and people from which Babylon rose, and, by extension, a way of speaking of Babylon itself and its empire. In Hebrew the people are Kasdim, and the same term stands behind the phrase "Ur of the Chaldees," the city from which Terah and Abram set out (Genesis 11:31) and which Nehemiah recalls as the place where God chose Abram (Nehemiah 9:7). Historically, the Chaldeans appear in Assyrian royal inscriptions from the ninth century BC onward as tribal and clan groups living in the marshy south near the head of the Persian Gulf, and the precise location of the city of Ur remains a matter of scholarly discussion. One linguistic detail: Jeremiah 51:1 addresses Babylon and "those who dwell in Leb-kamai," a coded form of "Kasdim" produced by a letter-substitution device that Jewish scribes used, so that the verse names Chaldea without naming it plainly.

The text also presents the Chaldeans as a military and imperial power. Second Kings describes raiding bands of Chaldeans sent against Judah (2 Kings 24:2) and Chaldean troops surrounding Jerusalem at the breach of the city wall (2 Kings 25:4); Chronicles says God brought "the king of the Chaldeans" against Jerusalem, who showed no compassion on young or old (2 Chronicles 36:17). Historically, this is the Neo-Babylonian empire, which took Babylon's independence after the fall of Assyria and reached its height under Nebuchadnezzar II, and Daniel 5:30 records the death of "Belshazzar the Chaldean King" on the night Babylon fell. In prophetic writing the name becomes almost a synonym for Babylon: Babylon is "the beauty of the Chaldeans' pride" (Isaiah 13:19), the Chaldeans are named among those who will flee the doomed city (Isaiah 43:14; 48:20), and the land of the Chaldeans is to be made desolate (Jeremiah 25:12; 51:24, 35).

Within Daniel the word carries a second sense. There "Chaldeans" are a professional class alongside magicians and enchanters, the court experts summoned to interpret dreams and inscriptions (Daniel 2:2; 4:7; 5:7), which is why the term is regularly rendered "astrologers" in that book; Daniel himself is trained in "the learning and language of the Chaldeans" (Daniel 1:4). Established scholarship recognizes both usages side by side: an ethnic designation and, in Daniel and later sources, a guild of diviners whose name derived from the reputation of Chaldean specialists in the stars.

Traditions read the term differently at a few points. Traditional readings take "Ur of the Chaldees" as a straightforward geographical notice tying the patriarchs to southern Mesopotamia, while historical-critical readers have often argued that the phrase reflects a later scribal updating, since the Chaldeans are not attested as a distinct people until centuries after the usual dating of Abraham, and they propose alternative locations for Ur. Readers also differ over Daniel's Chaldeans, some treating them as an ethnic group and others as a professional title for Babylonian diviners. Separately, "Chaldean" became the name of an Aramaic-speaking Christian body in Iraq in union with Rome, a later ecclesiastical usage with no direct link to the biblical ethnic term.
