TSK · Hebrews 7:13

It was a memorial for the Israelites, that no outsider who is not a descendant of Aaron should approach to burn incense before the LORD, that he might not become like Korah and his company– just as the LORD had spoken by the authority of Moses.

But once he became powerful, his pride destroyed him. He disobeyed the LORD his God. He entered the LORD’s temple to offer incense on the incense altar.

For it is clear that our Lord is descended from Judah, yet Moses said nothing about priests in connection with that tribe.
