Deuteronomy 32:43
Chapter 32 of Deuteronomy is titled, “The Song Of Moses” in my Bible. It started on the last verse of Chapter 31 by saying, “So Moses recited this entire song publicly to the assembly of Israel.” This happened AFTER Joshua became leader because Moses was about to pass away.
A lot of Moses song was the history of them leaving Egypt. There were some verses of the song that pointed to Jesus too. Verse 43 is the last part of the song and Moses mentions the angels. One of the things the angels do is worship God. And, God, in turn, strengthens the angels.
I’m sure there is much we will never know about the angels, but I’m thankful for these tidbits.
