In this week's Parsha, Pikudei, we read about the Mizbeach ha'Olah and Mizbeach for the Ketores. I have some thoughts and questions...
Were there only ever two?
Why is the Mizbeach ha'Olah called that when other, non-Olah offerings, like Shelamim, were brought as well?
Why was one put indoors, and one outdoors?
P.S. Bonus question: What happened when it rained? How would the Tamid and other outdoor offerings be brought?
