Land of Nod

The Land of Nod (Hebrew: אֶרֶץ־נוֹד‎ – ʾereṣ-Nōḏ) is a place mentioned in the Book of Genesis of the Hebrew Bible, located "on the east of Eden" (qiḏmaṯ-ʿḖḏen), where Cain was exiled by God after Cain had murdered his brother Abel. According to Genesis 4:16:

And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.^[1]
וַיֵּ֥צֵא קַ֖יִן מִלִּפְנֵ֣י יְהוָ֑ה וַיֵּ֥שֶׁב בְּאֶֽרֶץ־נֹ֖וד קִדְמַת־עֵֽדֶן׃‎

Genesis 4:17 relates that after arriving in the Land of Nod, Cain's wife had a son with him, Enoch, in whose name he built the first city.
