Selah (/( )/; Hebrew: סֶלָה, also transliterated as selāh) is a word used 74 times in the Hebrew Bible—seventy-one times in the Psalms and three times in the Book of Habakkuk. The meaning of the word is not known, though various interpretations are given below. (It should not be confused with the Hebrew word sela` (סֶלַע) which means "rock", or in an adjectival form, "like a rock", i.e.: firm, hard, heavy.) It is probably either a liturgico-musical mark or an instruction on the reading of the text, something like "stop and listen." Another proposal is that selah can be used to indicate that there is to be a musical interlude at that point in the Psalm. It can also be interpreted as a form of underlining in preparation for the next paragraph.
At least some of the Psalms were sung accompanied by musical instruments and there are references to this in many chapters. Thirty-one of the thirty-nine psalms with the caption "To the choir-master" include the word selah. Selah may indicate a break in the song whose purpose is similar to that of amen (Hebrew: "so be it") in that it stresses the truth and importance of the preceding passage; this interpretation is consistent with the meaning of the Semitic root ṣ-l-ḥ also reflected in Arabic cognate salih (variously "valid" [in the logical sense of "truth-preserving"], "honest," and "righteous"). Alternatively, selah may mean "forever," as it does in some places in the liturgy (notably the second to last blessing of the Amidah). Another interpretation claims that selah comes from the primary Hebrew root word salah (סָלָה), which means "to hang," and by implication "to measure (weigh)".
Its etymology and precise meaning are unknown. This word occurs seventy-one times in thirty-nine of the Psalms and three times in Habakkuk 3: altogether 74 times in the Bible. It is found at the end of Psalms 3, 24, and 46, and in most other cases at the end of a verse, the exceptions being Psalms 55:19, 57:3, and Hab. 3:3, 9, 13.
The significance of this term was apparently not known even by ancient Biblical commentators. This can be seen by the variety of renderings given to it. The Septuagint, Symmachus, and Theodotion translate διάψαλμα (diapsalma, or "apart from psalm") — a word as enigmatic in Greek as is selah in Hebrew. The Hexapla simply transliterates it as σελ (sel). Aquila, Jerome, and the Targum translate it as "always." According to Hippolytus (De Lagarde, "Novæ Psalterii Græci Editionis Specimen" 10), the Greek term διάψαλμα signified a change in rhythm or melody at the places marked by the term, or a change in thought and theme. Against this explanation, Baethgen ("Psalmen," p. 15, 1st ed. Göttingen, 1892) notes that selah also occurs at the end of some psalms.
One proposed meaning is given by assigning it to the root, as an imperative that should not properly have been vocalized, "sollah" (Ewald, "Kritische Grammatik der Hebräischen Sprache," p. 554; König, "Historisch-Kritisches Lehrgebäude der Hebräischen Sprache," ii., part i., p. 539). The meaning of this imperative is given as "Lift up," equivalent to "loud" or "fortissimo," a direction to the accompanying musicians to break in at the place marked with crash of cymbals and blare of trumpets, the orchestra playing an interlude while the singers' voices were hushed. The effect, as far as the singer was concerned, was to mark a pause. This significance, too, has been read into the expression or sign, selah being held to be a variant of "shelah" (="pause"). But as the interchange of shin (ש) and samek (ס) is not usual in Biblical Hebrew, and as the meaning "pause" is not held to be applicable in the middle of a verse, or where a pause would interrupt the sequence of thought, this proposition has met with little favor.
Grätz argues that selah introduces a new paragraph, and also in some instances a quotation (e.g., Psalms 57:8 et seq. from 108:2 et seq.) The fact that the term occurs four times at the end of a Psalm would not weigh against this theory. The Psalms were meant to be read in sequence, and, moreover, many of them are fragments; indeed, Psalm 9 is reckoned one with Psalm 10 in the Septuagint, which omits διάψαλμα (diapsalma) also at the end of Psalms 3, 24, 46 and 68 B. Jacob (l.c.) concludes (1) that since no etymological explanation is possible, selah signifies a pause in or for the Temple song; and (2) that its meaning was concealed lest the Temple privileges should be obtained by the synagogues or perhaps even by the churches.
The Brown-Driver-Briggs Hebrew and English Lexicon shows that the main derivation of the Hebrew word selah is found through the fientive verb root סֶ֜לָה which means "to lift up (voices)" or "to exalt," and also carries a close connotational relationship to the verb סָלַל, which is similar in meaning: "to lift up" or "to cast up." The word סֶלָה, which shifts the accent back to the last syllable of the verb form, indicates that in this context, the verb is being used in the imperative mood as somewhat of a directive to the reader. As such, perhaps the most instructive way to view the use of this word, particularly in the context of the Psalms, would be as the writer's instruction to the reader to pause and exalt the Lord.
Selah is used in Iyaric Rastafarian vocabulary. It can be heard at the end of spoken-word segments of some reggae songs. Its usage here, again, is to accentuate the magnitude and importance of what has been said, and often is a sort of substitute for Amen. Notable, according to Rastafarian faith, is also the word's similarity with the incarnated god and savior Selassie (Ethiopia's former emperor Haile Selassie).
Furman Bisher, the former sports editor and columnist for The Atlanta Journal-Constitution, for decades signed off his columns with "Selah." The same is often done by political columnist and blogger Ed Kilgore at the close of a day's postings.
