I must confess that I am predisposed to think of most of these as passages as teaching the preservation of scripture. Most of my teachers believed in the preservation of scripture, though they might not have agreed that all these texts do so -- and many could not be described as MT/TR or KJVO men.
That said, it seems like the main point of some of the texts is something like God saying, "I AM. What I say i
s truth. It does not matter what
you think or what
you say. Whatever
I say will stand.
Depend on it!!"
The first one on the list in Psalm 12:6-7. Here is the 12th Psalm.
Psalm 12 King James Version
1 Help, Lord; for the godly man ceaseth; for the faithful fail from among the children of men.
2 They speak vanity every one with his neighbour: with flattering lips and with a double heart do they speak.
3 The Lord shall cut off all flattering lips, and the tongue that speaketh proud things:
4 Who have said, With our tongue will we prevail; our lips are our own: who is lord over us?
5 For the oppression of the poor, for the sighing of the needy, now will I arise, saith the Lord; I will set him in safety from him that puffeth at him.
6 The words of the Lord are pure words: as silver tried in a furnace of earth, purified seven times.
7 Thou shalt keep them, O Lord, thou shalt preserve them from this generation for ever.
8 The wicked walk on every side, when the vilest men are exalted.
Viewed in the whole context of the song, I see verse 6 stating a general truth about God's words, and one that stands in contrast to speaking of men (as in vv. 2, 4). The words of the Lord are stated -- what he will do for the poor oppressed and needy. Because God's words are pure, they are dependable. You can believe the promise he makes in defense of the oppressed and needy toward those who are against them. The "them" in verse 7 then is most likely the oppressed and needy to whom he will keep his promise through the generations. If so, this text speaks of the general nature of God's words/promises, but the 7th verse wouldn't specifically apply to the preservation of the text of scripture. This is not to say that the purity of God's words has no implications on the idea of preservation.
(I just referenced this text a few days ago in arguing against Peter Ruckman's view of double inspiration and advanced revelation; I still think I am right and he is wrong, but I don't now think this text is applicable in the way I used it.)
By the way, I thought to look back at older commentators that lived before the version debate wars existed. Both John Gill and Matthew Henry thought the "them" in verse 7 applied to the people God would preserve and not the Bible. Interestingly, Gill's comments indicate he believes in preservation of the Bible, but not that this text teaches it:
Thou shall keep them, O Lord,.... Not the words before mentioned, as Aben Ezra explains it, for the affix is masculine and not feminine; not but God has wonderfully kept and preserved the sacred writings; and he keeps every word of promise which he has made; and the doctrines of the Gospel will always continue from one generation to another; but the sense is, that God will keep the poor and needy, and such as he sets in safety, as Kimchi rightly observes: they are not their own keepers, but God is the keeper of them; he keeps them by his power, and in his Son, in whose hands they are, and who is able to keep them from falling; they are kept by him from a total and final falling away; from the dominion and damning power of sin, and from being devoured by Satan, and from the evil of the world: and this the psalmist had good reason to believe, because of the love of God to them, his covenant with them, and the promises of safety and salvation he has made unto them;
And at an even earlier date and in a different language (though what I give is translated to English), John Calvin:
Some give this exposition of the passage, Thou wilt keep them, namely, thy words; (267) but this does not seem to me to be suitable. (268) David, I have no doubt, returns to speak of the poor, of whom he had spoken in the preceding part of the psalm.
There are other issues that relate to this that need fair examination as well. What does the loss of the book of the law in the house of God have to teach us about preservation (2 Kings 22)? What about Jehoiakim cutting up Jeremiah's prophecy and tossing it in the fire (Jeremiah 36)? I mention these because I think they militate against some of the ways we argue for preservation.
