Exodus 4:14
13 But Moses said, “O my Lord, please send anyone else whom you wish to send!” 14 Then the Lord became angry with Moses, and he said, “What about your brother Aaron the Levite? I know that he can speak very well. Moreover, he is coming to meet you, and when he sees you he will be glad in his heart. 15 “So you are to speak to him and put the words in his mouth. And as for me, I will be with your mouth and with his mouth, and I will teach you both what you must do.
Onkelos Exodus 4:14
13 And he said, I beseech the Lord to send by the hand of one who is fit to be sent. 14 And the anger of the Lord was kindled against Mosheh; and He said, Is not Aharon the Levite, your brother, known before Me as one who can speak well? and also, behold, he is coming to meet you, and will see you, and rejoice in his heart. 15 And you shall speak with him, and put the words in his mouth; and My Memra will be with your mouth and with his mouth, and I will teach you what to do.
Notes and References
"... The corporeality of God, a notion now rejected by most western religious traditions, was a widely held belief from pre-biblical times through the Middle Ages. Scripture supports this perception by frequently describing God in anthropomorphic terms (ascribing human attributes to God) and anthropopathisms (applying human emotions to God). Our targumist is among the earliest Bible exponents who vigorously rejected the belief that God was in any way corporeal. Among hundreds of changes in the translation to reflect Onkelos' views, we find that in verse 14 of this chapter, the active phrase 'I know,' which suggests the human process of acquiring knowledge, is softened to the passive 'it is revealed before Me' ..."
