The strategic deployment of anachronism in Jewish biblical interpretation reveals profound theological meaning beyond mere historical inaccuracy. The phrase "Ur of the Chaldeans" in Genesis offers a compelling case study of how temporal displacement serves vital religious and interpretive functions. Through close textual analysis of biblical passages, midrashic literature, and historical-critical scholarship, this investigation uncovers how the anachronistic reference to Chaldeans creates deliberate connections between Abraham's foundational journey and later Jewish exile experiences, particularly the Babylonian exile. The presence of this anachronism in both J and P sources underscores its integral importance to the text's meaning. Rabbinic midrash further developed Abraham's pre-biblical narrative by drawing upon later biblical portrayals of Chaldean Babylonia, transforming Abraham into an archetypal iconoclast who models Jewish distinctiveness in exile. Such anachronistic reading emerges as a legitimate and necessary aspect of Jewish tradition, enabling each generation to find contemporary relevance in ancient texts while preserving essential Jewish values and identity across historical periods.
