Torah is one of the Old Testament's most significant theological terms. While often translated 'law,' it fundamentally means 'instruction' or 'teaching.' It encompasses God's revealed will: specific commands, narrative, wisdom, and covenant relationship. Torah can refer to parental instruction, prophetic teaching, or most centrally, the Mosaic covenant. The word emphasizes guidance for life—not arbitrary rules but the path of wisdom and blessing. Post-exilic Judaism intensified focus on Torah study and observance as covenant identity.
