Selah

Selah (Hebrew: סֶלָה‎, also transliterated as selāh) is a word used 74 times in the Hebrew Bible – 71 times in the Psalms and 3 times in Habakkuk – and is a difficult concept to translate. (It should not be confused with the Hebrew word sela‘ (Hebrew: סֶלַע‎) which means "rock.") 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.
