This study examines the figures of theיקדִּ צַ and עשָׁ רָ in psalms. Drawing on both semantics and poetics, this study argues that the contrast between the figures represented by these terms is part of the conventions of Hebrew psalmody and, as such, can serve various discursive functions within an individual psalm. Using insights from the field of lexical semantics, the study clarifies the possible uses of the words Justand עשָׁ רָ, emphasizing a wider range of uses than is typically offered within a broad behavioral domain for these terms. The study summarizes ways that various books in the Hebrew Bible use the contrast of these figures to develop a description of the literary features related to their presentations. The analysis of 18 psalms that include both figures utilizes insights from narratological theories of character to explore the functions of the contrast between קידִּ צַ and עשָׁ רָ as literary figures within the overall discourse of the psalm. Focusing on the setting of an individual psalm and embracing the possibility of variation reveals that קידִּ צַ and עשָׁ רָ are not only, or even usually, employed to describe the “prototypically good” or “prototypically bad” person in psalms. Rather, the עשָׁ רָ is often a designation for an antagonist, and the קידִּ צַ is often understood as one who is innocently wronged. As such, the literary pattern of their contrast does not focus on the moral character of these figures but on the fairness or justice of God to eventually elevate the position of the קידִּ צַ and destroy the עשָׁ רָ.
