Selah

Selah (/ˈsiːlə/; Hebrew:סֶלָה‎, also transliterated as selāh) is a word used seventy-four times in the Hebrew Bible—seventy-one times in the Psalms and three times in 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‘ (Hebrew:סֶלַע‎) which means "rock". Moreso, in an adjective form that could be said "like a rock", ie: 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." Selah can also be used to indicate that there is to be a musical interlude at that point in the Psalm. The Amplified Bible translates selah as "pause, and think of that." It can also be interpreted as a form of underlining in preparation for the next paragraph.
