“Establish … a House of God”
Doctrine and Covenants 95; 109; 110;
Our Heritage, pages 33–36.
There’s a lot I’d like to say about this lesson on the LDS temple ceremonies, but I’ve already covered them in other lessons.
Here’s one, with a bit about the endowment: OT Lesson 30 (Temple)
And another, with a bit about the Hosanna Shout: OT Lesson 44.
I will get back to this at a later date, with more on this topic.
