How I discovered (see picture for result):
1. In the Box to the right of "Tools" type 2 Macc 12:43 (this will open a Catholic Bible; my top priority Bible is ESV, this opens NAB)
2. Then inside the NAB, go to Hebrews 12:29
3. Open Search panel, Bible search, NAB, All Passages. Search for Seraphim - 2 results.
4. Click on the first result, Isaiah 6:2. It moves the open NAB to Is 6:2, put the box at the top still says Hebrews 12:29
Note - I cannot get this to repeat! I am glad I got a picture of it:
