9 Therefore, you have delivered them up, yea, that which was sacred, unto wickedness.
Elder Paul B Pieper, To Hold Sacred, General Conference April 2012
Sacred means worthy of veneration and respect. By designating something as sacred, the Lord signals that it is of higher value and priority than other things. Sacred things are to be treated with more care, given greater deference, and regarded with deeper reverence. Sacred ranks high in the hierarchy of heavenly values.

9 And as they came down from the mountain, Jesus charged them, saying, Tell the avision to no bman, until the Son of man be risen again from the cdead.
3 Nephi 26;9-11
9 And now Alma began to expound these things unto him, saying: It is given unto many to aknow the bmysteries of God; nevertheless they are laid under a strict command that they shall not impart conly according to the portion of his word which he doth grant unto the children of men, according to the heed and diligence which they give unto him.
Men only receive what they have prepared themselves to receive. The rest they do not understand and are not given more of what God has for them.
Perhaps ones mind immediately flashes to the things of the temple when one reads this. I would propose that it is more expansive. There are times in the scriptures where the author states that they have been constrained from writing more. I would also propose that there are some int heir personal lives that have things that have been revealed to them that they feel constrained by the spirit to share, but under certain circumstances and not share them with the public at large.
Matthew 7: 6
6 ¶ aGive not that which is bholy unto the dogs, neither cast ye your cpearls before swine, lest they trample them under their feet, and turn again and rend you.
