Selah

Fausset's Bible Dictionary

Seventy-one times in the Psalms, three times in Habakkuk. From shelah , "rest." A music mark denoting a pause, during which the singers ceased to sing and only the instruments were heard. Septuagint diapsalma, a break in the psalm introduced where the sense requires a rest. It is a call to calm reflection on the preceding words. Hence, in Psalms 9:16 it follows eeiggaion , "meditation." The selah reminds us that the psalm requires a peaceful and meditative soul which can apprehend what the Holy Spirit propounds. Thus it is most suggestive, and far from being, as Smith's Bible Dictionary alleges of this sense, "superfluous." Delitsseh takes it from saalal "to lift up," a musical forte, the piano singing then ceasing, and the instruments alone playing with execution an interlude after sentences of peculiar importance, so as to emphasize them.
