The scales in a dream indicate the judge, the scholar, or religion and justice. Its balance indicates the straightness of religion and justice. Its tilting indicates injustice and misguidance.

The scales indicate guidance. Whoever sees scales in his hand is on the path of truth. The beam of the scales is the tongue of truth.

The scales are interpreted as the king or ruler. What is weighed with it indicates judgments. Whoever sees his scale tip in his favor, his argument is stronger.
