Zechariah 4:6 - Bible study

When God says in Zechariah 4:6 "not by might, not by power but by My Spirit says The Lord of Hosts".  The fact He called Himself "Lord of 'hosts' in this particular scenario caught my attention.  When God uses a specific title for Himself, the context surrounding the usage is very critical in understanding what He is speaking to us.  As I read this what came to me was that He is talking about His spirit.  A spirit needs a host.  Think about how we use the word "host". Like when you host something at your house.  You are welcoming people inside your home and serving them.  Our bodies can be used as a  host for the Holy Spirit or for evil spirits.  But, whether you host evil spirits or the Holy Spirit,  God is still Lord.  He is The Lord over every host.  But I believe He needed to say this because He is talking about His spirit here and Christians are, in a sense, "hosts" to the Holy Spirit.  But I also think he said this because He uses the word power here; and "hosts" as it is used in this scripture also comes from a primary root in the Hebrew, meaning mass of persons like army or servants.  God is saying that my Spirit is in You and I'm The Lord of you and I'm going to work in your life through my spirit because you are my host.  But He is also referring to the army of hosts that serve Him.  An army that we cannot see.  I believe although He says "not by power"; He is referring to human strength, but He points to His power here referring to His spirit in us as well as the huge number which forms His army of heavenly hosts.  They work for God on behalf of His people.

¹³ But to which of the angels has He ever said:

“Sit at My right hand,
Till I make Your enemies Your footstool”?^[i]

¹⁴ Are they not all ministering spirits sent forth to minister for those who will inherit salvation?
