In the Damascus Document V:1-5, we read the following which is similar to what one finds in D&C 132 concerning David's polygamy:
1 and those who went into the ark ‘two by
two they went into the ark.’ <And concerning the prince, it is written:
2 ‘He shall not multiply wives for
himself’; but David had not read the sealed book of the law which
3 was in the ark (of the covenant), for it
had not been opened in Israel since the deaths of Eleazar,
4 Joshua and the Elders, because (during
this time) they were worshipping Ashtoreth; so it was hidden
5 (and not) revealed until Zadok arose.
Hence the deeds of David were overlooked, except the blood of Uriah

As
John Tvedntes noted, the text above is also evidence of “hidden books” in
antiquity.
