The Lord of Hosts
The Lord of Hosts is the name God wages warfare on behalf of His people. He reveals Himself as our faithful defender and the one who establishes justice for us.
There is also an indication of involvement associated with this name, for He is identified as our Redeemer. Isaiah 44:6 "Thus says the Lord, the King of Israel, and his Redeemer, the Lord of hosts:
I am the First and I am the Last; Besides Me there is no God."
More specifically, He is our Kinsman Redeemer, the one who acts on behalf of his next of kin, to ransom, redeem, or deliver. A kinsman redeemer would buy back his relative's property or marry his widow, for the sake of the family and to protect their inheritance.
The Lord of Hosts is also identified as our husband. Isaiah 54:5 "For your Maker is your husband, The Lord of hosts is His name".
