The YHWH-mlk-psalms (Pss 47, 93, 96-99) are some of the best-known psalms in the Old Testament. The terminology, themes, images and ideas within these psalms suggest the existence of a strong common link. Since the beginning of the last century the YHWH-mlk-psalms were the focus of a lot of research. A variety of different backgrounds for the interpretation of these psalms have been suggested. Despite the large quantities of research done on the YHWH-mlk-psalms, there is still no consensus on how these psalms should be interpreted. The YHWH-mlk-psalms show various monotheistic characteristics of which the YHWH-mlk-reference (Pss 47:3; 93:1; 96:10; 98:6; 99:1, 4) forms only one example. This article proposes that the YHWH-mlk-psalms be studied against the background of the development of monotheism in Israel. The results of such a study would contribute to the better understanding of these psalms.
