Exodus 7:1
1 So the Lord said to Moses, “See, I have made you like God to Pharaoh, and your brother Aaron will be your prophet. 2 You are to speak everything I command you, and your brother Aaron is to tell Pharaoh that he must release the Israelites from his land. 3 But I will harden Pharaoh’s heart, and although I will multiply my signs and my wonders in the land of Egypt,
Onkelos Exodus 7:1
1 But the Lord said to Mosheh, See, I have appointed you a Teacher to Pharoh, and Aharon shall be your interpreter. 2 You shall speak all that I have commanded you, and Aharon thy brother shall speak with Pharoh to send away the sons of Israel from his land. 3 And I will harden the heart of Pharoh, and will multiply My signs and wonders in the land of Mizraim.
Notes and References
"... It is not always easy to understand the Bible, especially when it uses Hebrew words that have different meanings in different contexts. Onkelos usually attempts to mitigate the confusion that this may cause. In verse 7:1, for example, God addresses Moses saying, 'I have appointed you as Elohim [normally: 'God'] to Pharaoh, and Aaron your brother will be your navee [customarily translated as 'prophet'. Onkelos translates this in an unambiguous fashion, rendering Elohim as 'teacher,' to avoid the misunderstanding that God might be deifying Moses, and navee as 'translator,' since that would be Aaron's essential function ..."
