Exodus 3:18 KJV
18 And they shall hearken to thy voice: and thou shalt come, thou and the elders of Israel, unto the king of Egypt, and ye shall say unto him, The LORD God of the Hebrews hath met with us: and now let us go, we beseech thee, three days' journey into the wilderness, that we may sacrifice to the LORD our God.
More than ten times Moses appears before Pharaoh but he only brings his brother Aaron
Exodus 5 KJV
And afterward Moses and Aaron went in, and told Pharaoh, Thus saith the LORD God of Israel, Let my people go, that they may hold a feast unto me in the wilderness.
Exodus 7 KJV
10 And Moses and Aaron went in unto Pharaoh, and they did so as the LORD had commanded: and Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent.
Exodus 10 KJV
3 And Moses and Aaron came in unto Pharaoh, and said unto him, Thus saith the LORD God of the Hebrews, How long wilt thou refuse to humble thyself before me? let my people go, that they may serve me.
In all instances when Moses came before Pharaoh there is no mention of him bringing the elders to meet Pharaoh.
Did Moses disregard God's command to bring along the elders to meet Pharaoh?
