Scholarship assumes no significant differences among various “terms for anger” in the Hebrew Bible, but it does assume an essential difference between human and divine anger. This article challenges these preconceptions by presenting a novel semantic analysis of כעס, considered a “term for anger.” It shows that in Classical Biblical Hebrew, כעס does not denote anger but rather sorrow or insult associated with קנאה, “jealousy.” This analysis leads to a new, deeper, and more precise understanding of the phrase “to cause כעס to Yhwh” and of its meaning in biblical literature and theology in general and in Deuteronomistic writings in particular.
