You have no scriptures that says the Greek and Hebrew are the only languages where God's words are preserved.
You are battling for the acceptance of a doctrine that is not in the scriptures.
Your opinion is incorrect. There is more scriptural support for my accepting what the Scriptures teach in relationship to preservation than there is for recent or modern KJV-only opinions concerning it.
Do you suggest that you do not believe the words "written by the prophets" (Luke 18:31) which would refer to the actual specific words directly written by the prophets in the original languages in which God gave them by inspiration?
The exact, specific words spoken by Paul and other apostles by means of the Holy Spirit and later written referred to those words that were written in the original languages (1 Cor. 2:13, 2 Pet. 1:21, 2 Pet. 3:16, 2 Pet. 3:2, John 17:8, Luke 18:31, Heb. 1:1-2). The Lord Jesus Christ directly referred to “the things that are
written by the prophets” (Luke 18:31), and the actual words directly written by the prophets themselves would have been in the original language in which God gave them by inspiration to the prophets. The oracles of God [the Old Testament Scriptures] given to the prophets were committed unto the Jews in the Jews‘ language (Rom. 3:2, Matt. 5:17-18, Luke 16:17). The specific features “jot“ and “tittle“ at Matthew 5:18 and the “tittle” at Luke 16:17 would indicate the particular original language words of the Scriptures given by inspiration of God to the prophets and would state something about language and about the preservation of the Scriptures.
That which was spoken of the Lord by the prophet would be in the original language in which it was given by inspiration (Matt. 1:22, Matt. 2:15). The actual, specific, exact words which the LORD of hosts sent in His Spirit by the prophets would be in the original language in which God gave them (Zech. 7:12). The actual words written by the prophet would be in the same language in which he originally wrote them (Matt. 2:5, Luke 18:31). The exact words which “the prophets and Moses did say” (Acts 26:22) would be in the same language in which they stated them. Which are the same words spoken by the mouth of all his holy prophets (Acts 3:21)? Would not the words spoken by the LORD by the prophets be in the language in which God gave them (2 Kings 21:10, 2 Kings 24:2)? It would be sound and true to conclude that the actual words of the prophets themselves would be in the original language in which they were given (Acts 15:15). The scriptures of the prophets (Rom. 15:26) would be in the language in which they were given to them.
The actual words of Haggai the prophet would be in the language in which he spoke or wrote them (Haggai 1:12). The scroll of the LORD to be sought and read at the time that Isaiah the prophet wrote would have been a scroll written in Hebrew (Isa. 34:16). The apostle John referred to his own actual words he himself was writing in the language in which he wrote them (1 John 2:12-14). “Moses wrote all the words of the LORD” (Exod. 24:4). The Lord Jesus Christ stated: “For had ye believed Moses, ye would have believed me: for he wrote of me. But if ye believe not
his writings, how shall ye believe my words?” (John 5:46-47). In another apparent reference to the writings of Moses, Jesus asked the Pharisees concerning whether they had not read them (Matt. 19:4, 7-8, Luke 10:26). The actual writings of Moses referred to by Jesus would have to be in the original language in which Moses directly wrote them. The word of the LORD by the hand of Moses (2 Chron. 35:6, Num. 4:45) would be in the original language in which Moses spoke or wrote it. The LORD commanded by the hand of Moses (Lev. 8:36, Num. 4:37, Num. 15:23, Num. 27:23), and the LORD had spoken by the hand of Moses (Lev. 10:11). In what language were the actual words written by the hand of Moses? When later Jewish scribes made a copy of the writings of Moses, they copied his same words in the same language in which Moses had originally written them.
Do these Scripture passages teach or at least clearly infer that the doctrine of preservation would concern the actual specific original-language words given by inspiration of God to the prophets and apostles?
