Exodus 6:21

And the sons of Izhar; Korah, and Nepheg, and Zichri.

The book that holds this verse is about going out, the departure of Israel from Egypt. Its name itself means that going out. This verse stands in the historical part of that book, which covers chapters 1 to 18.

It belongs to the account of the family of Israel grown greater and mightier than the Egyptians while held in bitter bondage and oppression, and then brought through great deliverance. That setting shows how they became a nation with thorough organization, effective leadership, a complete code of laws, and an established form of worship. Its context centers on the life of Moses, from his rescue in infancy from Egyptian hostility, as the chosen leader of Israel.
