Michtam: Writing; i.e., a poem or song found in the titles of
(Psalms 16:1; 56:1)
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."
