אֱדוֹם (e.dom)

The Hebrew word Edom literally means "red," a name given to Esau at birth because he emerged from the womb covered in reddish hair, as recorded in Genesis 25:25. This simple descriptor quickly became a proper noun, identifying not only the twin brother of Jacob but also his descendants and the rugged territory they inhabited south and southeast of Palestine.

Over time, the term expanded to cover both the people and the place. In passages like Psalm 137:7, Edom represents the nation that rejoiced over Jerusalem’s fall, while in texts such as Genesis 36:16, it denotes the mountainous region known later as Idumea. The distinction between the person, the ethnic group, and the land is fluid, with context determining whether the focus is on Esau himself, his lineage, or their geographic domain.

Translators consistently render this word as "Edom" rather than translating it as "red," preserving its identity as a specific historical and geographical entity. The name serves as a constant reminder of the origin story of two nations whose relationship would be defined by rivalry and conflict for centuries, rooted in that initial moment of birth.
