“Numberless Concourses of Angels”

"This expression reminds us, perhaps, of Daniel who saw 'the Ancient of Days' on his throne: 'Thousand thousands ministered unto him, and ten thousand times ten thousands stood before him.' [Daniel 7:9-11] All ready to carry out his commandments. Daniel says, 'the judgment was set and the books were opened.' Or, as we should say, the court was in session. Judgment was about to be pronounced upon the 'four beasts,' that is, the Babylonian, the Medo-Persian, the Macedonian and the Roman Empires."

"The vision of Lehi was analogous to this. But the impending judgment in his vision was upon Judah and Jerusalem, and not upon pagan empires." (Commentary on the Book of Mormon, ed by George Reynolds, Janne Sjodahl, and Phillip Reynolds, chap. 1, p. 9)
