The Lord bless His angels. What does the scripture talk about, if regarding the upper angels, it is already said "all His host"? It only speaks of the lower angels. And how do we know that the lower angels are called angels?
As it is said (Numbers 20:16), "And He sent His angel and took us out of Egypt." But was it really an angel, and not Moses? Rather, the prophets are called angels. And it is also said (Haggai 1:13), "And Haggai, the angel of the Lord, spoke."
Rabbi Judah bar Simon said (Judges 2:1), "And the angel of the Lord went up from Gilgal to Bochim." This refers to Phinehas. But the sages say, "What did the wife of Manoah say to him?" (Judges 13:6), "Behold, a man of God came to me, and his appearance was like the appearance of an angel of God, very awe-inspiring." She thought he was a prophet and not just an angel.
You must therefore conclude that the prophets are called angels. Rabbi Huna said in the name of Rabbi Aha, "They were explained at Sinai." Mighty are the doers of His word, to hearken to the voice of His word. They performed an action before they listened to it.
As it is said (Exodus 24:7), "All that the Lord spoke, we will do and we will hear." Rabbi Isaac said, "It speaks of those who keep the sabbatical year." In the usual practice of the world, one performs a commandment for an hour, a day, a Sabbath, or a month, perhaps for a year. But Israel does so for seven years.
Rabbi Tanhum bar Hanilai said, "Mighty are the doers of His word," refers to Moses, for there is no mightier person than Moses, as Israel stood before Mount Sinai and could not hear the utterance, as it is said (Deuteronomy 5:22), "If we hear the voice of the Lord our God any more, we shall die." But it is written (Exodus 20:16), "Come close, and hear." That which sixty myriads were unable to hear, Moses heard for himself, and the voice called to him (Leviticus 1:1), "And He called to Moses," and he was not harmed.
This teaches you that the righteous are greater than ministering angels, for they can only hear His voice and quake and tremble, while the righteous can hear His voice, as it is said (Joel 2:11), "The Lord gives voice before His army, for His camp is very great." These are the angels referred to as "the camp of God" (Genesis 32:2). And it is written "A thousand thousands ministered to Him" (Daniel 7:10), and who can hear His voice?
"For His deeds are mighty" (Joel 2:11), as He is greater than the ministering angels. And who is this Moses who heard the voice of God? As it says "And the Lord called to Moses" (Exodus 19:3). Behold, he is a hero of great strength - this is Moses.
