“What does ‘selah’ mean in the Bible?”
The word “selah” is found in two books of the Bible, but is most prevalent in the Psalms, where it appears 74 times. It also appears three times in the third chapter of the minor prophet Habakkuk.
“Selah” is thought to be rendered from two Hebrew words: s_lah, “to praise”; ands_lal, “to lift up.” Another commentator believes it comes from salah, “to pause.” From these words comes the belief that “selah” is a musical direction to the singers and/or instrumentalists who performed the Psalms, which was the hymnbook of the Israelites. If this is true, then each time “selah” appears in a psalm, the musicians paused, either to take a breath, or to sing a cappella or let the instruments play alone. Perhaps they were pausing to praise Him about whom the song was speaking, perhaps even lifting their hands in worship. This would encompass all these meanings—praise, lift up, and pause. When we consider the three verses in Habakkuk, we also see how “selah” could mean “to pause and praise.” Even though Habakkuk was not written to be sung, Habakkuk’s prayer in chapter 3 inspires the reader to pause and praise God for His mercy, power, sustaining grace and sufficiency.
Perhaps the best way to think of “selah” is a combination of all these meanings. The Amplified Bible adds “pause and calmly think about that” to each verse where “selah” appears. When we see the word in a psalm or in Habakkuk 3, we should pause to carefully weigh the meaning of what we have just read or heard, lifting up our hearts in praise to God for His great truths. “All the earth bows down to you; they sing praise to you, they sing praise to your name.” Selah! (Psalm 66:4).
