ONE GOD - manifested in three persons - Father, Son, and Holy Spirit.
Jesus is the God of the Burning Bush (John 8:58, etc.).
You should also do a study on "THE Angel ("Messenger") of the Lord" so you can see it is Christ in the Burning Bush that Moses encountered.
THE Angel of the Lord
Angel of the LORD | Precept Austin
Excerpts:
"Angel in both Hebrew (malak) and Greek (aggelos or angelos)
means a messenger and Jesus as the Word of God (Jn 1:1; Re 19:13-note) is the ultimate Messenger sent from the Father with a message of the good news of God's covenant love for sinful mankind..."
"Behold, I am going to send My messenger (Hebrew = malak = one sent on business or diplomacy by another; LXX = aggelos/angelos one sent to tell or bring a message, to announce or proclaim = transliterated "angel" and in context referring to John the Baptist, as affirmed by Jesus Himself in Lk 7:27) and he (John the Baptist) will clear the way before Me (the LORD of hosts) and the Lord (Hebrew = adon, LXX = referring in context to the Messiah), Whom you seek, will suddenly (Hebrew = pitom = unexpectedly, surprisingly, all of a sudden - somewhat an ironic word here because the Jews should have known the day of His visitation according to Lk 19:44), which they could have known by studying Da 9:24, 25, 26, 27 {see notes Da 9:24; 25; 26; 9:27}) come to His temple and the MESSENGER OF THE COVENANT, (Malak = "Angel"; and thus the "Angel of the Covenant") in Whom you delight, behold, He is coming," says the LORD of hosts. (Malachi 3:1-see commentary)"
Malachi 3:1 is a prophecy about Jesus.
"I will send my
messenger ("malak" - same word as angel), who will prepare the way before me. Then suddenly the Lord you are seeking will come to his temple; the messenger of the covenant, whom you desire, will come," says the LORD Almighty."
