The division of Isaiah into chapters and verses is a Christian invention. The context of Chapter 53 is set out in Chapter 48 where Isaiah describes his mission as the messenger of God, and God says to Israel, “You are My servant, Israel, about whom I will boast.”
Could you please cite the first place where any real estate was called Israel? It is NO Christian invention that after Solomon, there was a 'civil war' and the 12 tribes became divided. The land was called Judah and Samaria. According to the Scripture the House of Judah and the House of Israel will not be rejoined until the return of Christ. Did not Isaiah live/write after Solomon?
Jeremiah pens that God divorced the House of Israel ... because of their whoredoms and 'spiritual' adultery... the punishment was that those children of the House of Israel would not even know who they were... That part has sure been fulfilled.
Furthermore, Moses named each individual tribe and what their future would hold, individually.
If we have to accept the suffering servant of Isaiah 53 with the servant of Isaiah 48, then who is being spoke of in Isaiah 28? Is this one person or perhaps two? Is this two people being addressed by the same name? Are they from the same timeline?
Isaiah 28
1 The word of the LORD came again unto me, saying,
2 Son of man, say unto the prince of Tyrus, Thus saith the Lord GOD; Because thine heart is lifted up, and thou hast said, I am a God, I sit in the seat of God, in the midst of the seas; yet thou art a man, and not God, though thou set thine heart as the heart of God:
3 Behold, thou art wiser than Daniel; there is no secret that they can hide from thee:
4 With thy wisdom and with thine understanding thou hast gotten thee riches, and hast gotten gold and silver into thy treasures:
5 By thy great wisdom and by thy traffick hast thou increased thy riches, and thine heart is lifted up because of thy riches:
6 Therefore thus saith the Lord GOD; Because thou hast set thine heart as the heart of God;
7 Behold, therefore I will bring strangers upon thee, the terrible of the nations: and they shall draw their swords against the beauty of thy wisdom, and they shall defile thy brightness.
8 They shall bring thee down to the pit, and thou shalt die the deaths of them that are slain in the midst of the seas.
9 Wilt thou yet say before him that slayeth thee, I am God? but thou shalt be a man, and no God, in the hand of him that slayeth thee.
10 Thou shalt die the deaths of the uncircumcised by the hand of strangers: for I have spoken it, saith the Lord GOD.
11 Moreover the word of the LORD came unto me, saying,
12 Son of man, take up a lamentation upon the king of Tyrus, and say unto him, Thus saith the Lord GOD; Thou sealest up the sum, full of wisdom, and perfect in beauty.
13 Thou hast been in Eden the garden of God; every precious stone was thy covering, the sardius, topaz, and the diamond, the beryl, the onyx, and the jasper, the sapphire, the emerald, and the carbuncle, and gold: the workmanship of thy tabrets and of thy pipes was prepared in thee in the day that thou wast created.
14 Thou art the anointed cherub that covereth; and I have set thee so: thou wast upon the holy mountain of God; thou hast walked up and down in the midst of the stones of fire.
15 Thou wast perfect in thy ways from the day that thou wast created, till iniquity was found in thee.
16 By the multitude of thy merchandise they have filled the midst of thee with violence, and thou hast sinned: therefore I will cast thee as profane out of the mountain of God: and I will destroy thee, O covering cherub, from the midst of the stones of fire.
17 Thine heart was lifted up because of thy beauty, thou hast corrupted thy wisdom by reason of thy brightness: I will cast thee to the ground, I will lay thee before kings, that they may behold thee.
18 Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
19 All they that know thee among the people shall be astonished at thee: thou shalt be a terror, and never shalt thou be any more.
I contend that this is a case where the Bible begins a story using one person as the main character, only to use him figuratively for someone else.
8 But you, Israel My servant, Jacob whom I have chosen, the seed of Abraham, who loved Me,
9 Whom I grasped from the ends of the earth, and from its nobles I called you, and I said to you, "You are My servant"; I chose you and I did not despise you.
10 Do not fear for I am with you; be not discouraged for I am your God: I encouraged you, I also helped you, I also supported you with My righteous hand.
11 Behold all those incensed against you shall be ashamed and confounded; those who quarreled with you shall be as nought and be lost.
12 You may seek them but not find them, those who quarrel with you; those who war with you shall be as nought and as nothing.
