Easton's Bible Dictionary (1897)
Writing; i.e., a poem or song found in the titles of Ps. 16; 56-60. 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.”
Smith's Bible Dictionary (1863)
(golden psalm). This word occurs in the titles of six psalms (16,56-60), all of which are ascribed to David. The marginal reading of our Authorized Version is “a golden psalm,” while in the Geneva version it is described as “a certain tune.” From the position which it occupies in the title we may infer that michtam is a term applied to these psalms to denote their musical character, but beyond this everything is obscure.
Hastings' Dictionary of the Bible (1898)
MICH'TAM occurs in the inscriptions of six Psalms - namely, 16 and 56-60 - but its true meaning is doubtful. Some derive it from a root denoting gold, and our translation gives it in the margin as "the golden Psalm." More probably, however, it is a musical expression whose signification has been lost.
