Easton’s Bible Dictionary – Michtam (Miktam)

writing; i.e., a poem or song found in the title of Psalm 16. Some translate the word "golden", i.e., precious. It is rendered in the LXX. by a word meaning "tablet inscription" or a "stelograph." The root of the word means to stamp or grave, and hence it is regarded as denoting a composition so precious as to be worthy to be engraven on a durable tablet for preservation; or, as others render, "a psalm precious as stamped gold," from the word kethem , "fine or stamped gold."
