I found this interesting, John. I hope you won't mind that I'm taking a closer look at it here.
... Here is what I put together once listing people in the Word of God who took responsibility to preserve the Word:
Bible Examples of Human Preservation of the Scriptures
A. God commanded the Jews to bind God's law on their hands and on their foreheads (Ex. 13:9, Deut. 6:8 & 11:8, Prov. 3:3, 6:2, 7:3).
Of course, it probably was not God's intention that they literally bound it to themselves. For example, I've never seen a Jew physically put a book of the Scriptures into their mouth, or suggest that they had surgically inscribed words on their internal organs (Exodus 13:9, & Proverbs 7:3, KJV) --
And it shall be for a sign unto thee upon thine hand, and for a memorial between thine eyes, that the LORD'S law may be in thy mouth: for with a strong hand hath the LORD brought thee out of Egypt.
Bind them upon thy fingers, write them upon the table of thine heart.
What God wanted was for His people to
remember and obey His word. Nonetheless, the Jews did preserve a small amount of written Scripture in this manner. [Check your references: "Deut. 11:8" should be 11:18, and Prov. 6:2 doesn't seem right.]
... B. Each king of Israel was required to write out his own copy of the Bible. "And it shall be, when he sitteth upon the throne of his kingdom, that he shall write him a copy of this law in a book out of that which is before the priests the Levites" (Deut. 17:18). Not only was he to have his own copy of the law, he was to live and rule by it (v. 19).
The use of the word "Bible" in your statement tends to sound anachronistic. The Torah is actually all that the kings would have had to copy. God primarily intended that the leadership would
learn ("
learn to fear the LORD his God", v.19) through this exercise. However, not all kings complied. Nonetheless, a few additional copies of Scripture were preserved due to this requirement. We might wonder though, how accurate were those king's copies?
... C. Moses cared enough about the Decalogue to make a box of shittim wood in which to preserve it (Deut. 10:3-5).
Actually, God
commanded Moses to make the wooden ark (10:1) in which to place the stone tablets. The box may have protected the tablets to some degree. Of course, this is not an example of 'preservation' in the sense of contributing new copies.
... D. The ark of God was called variously "the ark of the testimony" (Josh. 4:16) and "the ark of the covenant" (Josh. 4:18), obviously referring to the fact that God's Word was to be kept inside it (Deut. 31:26).
We are told the stone tablets were placed in the ark by God's command. The tablets were ceremoniously shut up in the ark, unaccessible for reading or copying. Similar to C above, this is not an example of 'preservation' in the sense of continuing a manuscript tradition.
... E. God commanded the Jews to build an altar and write the law on the stones of it when they crossed the river into the Promised Land. (Deut. 27:1-8) Joshua obeyed God's command and did so (Josh. 8:30-35).
The immediate crossing of Jordan is not the fulfillment of "Deut. 27:-8". To avoid confusion, the 12 stones at Jordan are not said to have had any writing inscribed into them (Joshua 4:8-9) --
And the children of Israel did so as Joshua commanded, and took up twelve stones out of the midst of Jordan, as the LORD spake unto Joshua, according to the number of the tribes of the children of Israel, and carried them over with them unto the place where they lodged, and laid them down there.
And Joshua set up twelve stones in the midst of Jordan, in the place where the feet of the priests which bare the ark of the covenant stood: and they are there unto this day.
The fulfilling event does seem to be "Josh. 8:30-35" which actually follows the Hebrew's victory over the city of Ai. These exposed stones may have preserved the words for a while, but one immobile copy does not contribute much to the ongoing preservation effort. It seems to be more for
commemorative purposes.
... F. The Apostle Paul specifically asked Timothy to bring his personal copy of some of the Old Testament Scriptures. (2 Tim. 4:13).
This doesn't seem to be an additional example of preservation, but rather simply transportation of already existing copies.
