There are numerous biblical incidents that involve the Sons of Korah as side figures that would not be notable unless one happens to know the identity of the Sons of Korah. One of those incidents is an obscure incident that takes place in Jeremiah 35:4, when the Rechabites show their loyalty to their father Jonadab, who had lived about 150 years beforehand.
Jeremiah 35:3-4 reads: “Then I took Jaazaniah the son of Jeremiah, the son of Habazziniah, his brothers and all his sons, and the whole house of the Rechabites, and I brought them into the house of the Lord, into the chamber of the sons of Hanan the son of Igdaliah, a man of God, which was by the chamber of the princes, above the chamber of Maaseiah the son of Shallum, the keeper of the door.” This is a very straightforward incident. It is beyond the scope of this particular note to examine that incident in depth, except to note that the loyalty given by the Rechabites to Jonadab prompted God to bless them.
What was the role of the Sons of Korah in this incident? It was a small role, simply serving their duties in the temple as gatekeepers, allowing Jeremiah the space to use above their chambers for a prophetic demonstration of God’s rewarding of those who honored their fathers in contrast to a nation that dishonored their God. It is not a grand or a big task, but for doing their job well, Maaseiah the son of Shallum the Korahite gets mentioned here in the Bible.
Of course, most of the people who read this chapter would be completely unaware that it involved the sons of Korah, because even though the duties of the Sons of Korah are clearly spelled out in the Bible , most people do not read those portions of scripture, or follow the links and connections of that particular group of people even though they are numerous and even though their service is notable. Nonetheless, let us take pleasure at least in showing the thread of the sons of Korah even in relatively minor ways, such as being present in their duties as temple gatekeepers and allowing a prophet to do a demonstration above their quarters.
