A word frequently found in the Book of Psalms, and also in Hab. 3:9, 13, about seventy-four times in all in Scripture. Its meaning is doubtful. Some interpret it as meaning "silence" or "pause;" others, "end," "a louder strain," "piano," etc. The LXX. render the word by daplasma i.e., "a division." the end; a pause This word, which is found only in the poetical books of the Old Testament, occurs seventy-one times in the Psalms and three times in Habakkuk. It is probably a term which had a meaning in the musical nomenclature of the Hebrews, though what that meaning may have been is now a matter of pure conjecture. (Gesenius and Ewald and others think it has much the same meaning as our interlude,--a pause in the voices singing, while the instruments perform alone.)
