How do we know Jesus is the Lord of Hosts?

Scripture consistently reveals that the Lord of Hosts, whom Isaiah saw exalted in Isaiah 6, is indeed the pre-incarnate Christ. As cited in Isaiah 44:6 and Isaiah 54:5, He is referred to as the Redeemer and the Holy One of Israel. This dual recognition in both the Old and New Testaments showcases the continuity of God's revelation; Jesus embodies all that God is, particularly His holiness, authority, and redemptive purpose. Furthermore, in John 14:9, Jesus Himself states, 'He that hath seen me hath seen the Father,' affirming His identity as the Lord of Hosts.
