Ex. 4:17 who is holding the rod?

This is a little deeper to understand but is very good to understand.
Many times Moses commanded to stretch forth his hand holding the rod God told him would do wonders.

In Isa. 11:1  is the prophesy that a rod would come forth from Jesse. He would be called the branch. David Jesse's son has already lived and gone on.   In those days all people came under one name.  There was no last name.  You were of Israel and called of  David.  Jesus was of Israel.
Like Moses the saints who overcome in the end,  Rev. 2:27,  will rule also with a rod of iron.  the second part of v.27  shows it  isn't  Jesus. but it is Jesus there in the second part.  Must read all around that verse to see he's talking to the church.  v.26  they who overcome will also rule nations.
see also Jer. 23:5  the branch.

The bride and the bridegroom will come together and  rule in the Millenium.    Yet we are still called kings and priests   do know there is neither male nor female distinction there.  All are the bride of Christ.
see  1Cor, 4:8,     2Tim. 2:12,      Rev. 5:10   we shall reign with him on earth.  This passage  is future. All after ch.4 is.
Rev. 20:6   reign with him a 1,000 years.
