Okay, so back in the olden days, there were a lot of religious books called the Hebrew Bible or the Old Testament. And in one of those books called the Psalms, there's a special Hebrew word called "selah" that pops up a lot.
Now, "selah" doesn't have an exact translation in English, but it's kind of like a musical term that means to pause and think for a moment. It's like when you're singing a song and there's a line that's really important, so you stop singing for a sec to let it sink in.
In the Psalms, selah usually appears at the end of a verse or a line of poetry. It's almost like a little reminder to take a break, breathe, and really ponder what was just said. Some people think that it also signaled a musical interlude, where the singer or musician could improvise or embellish on the melody while the audience reflected on the words.
So, even though Selah was not a person or a figure in the Bible, it was a really important word that helped people connect with their faith and engage with the words they were reading or singing. Cool, huh?
