Oral communication through angels. For example, God used an angel to instruct Moses about the message he was to deliver to Pharaoh of Egypt. (Exodus 3:​2-4, 10) When precise wording was crucial, God directed angels to dictate his message, as he did when he told Moses: “Write down these words, because in accordance with these words, I am making a covenant with you and with Israel.”​—Exodus 34:27.a
