What does Exodus 4:14 mean?
This reveals two aspects of God's divine nature. First, He can experience anger. Throughout the Old Testament the "anger of the Lord" is mentioned more than thirty times, as a response to human sin or stubbornness. Even heroic figures like Moses are not immune to the Lord's irritation.Second, God reveals His "providence," which means His power to arrange circumstances according to His will. Moses' brother, Aaron, is either already headed Moses' way, or will meet him shortly. The Hebrew phrasing can mean either something happening in the near future, or a suggestion that this is already happening.
Aaron was approximately three years older than Moses (Exodus 7:7) and apparently born prior to Pharaoh's command to throw newborn Jewish sons into the Nile (Exodus 1:22). Their family were Levites (Exodus 2:1). Aaron would later become the first high priest of the Jews as a member of this priestly tribe. That he was coming to meet Moses implied God had led Aaron as well. That Aaron would be glad to see his brother suggests a level of care and concern.
According to the Lord, Aaron could speak well. This trait would serve as an important aspect of Aaron's work before Pharaoh and later in his role as priest. In fact, most of the words "spoken" by Moses in public settings would have been delivered by Aaron (Exodus 4:15–16).
