Idk who said it, but I remember very clearly learning it at the COGIC church. The first time they ever put me on program to read a scripture, the church mother (who I really thought hated me, but she didn't) pulled me over (literally PULLED me) when she saw my name on the program and asked me what scripture I "thought" I was going to read (in other words, I'm finna change your scripture but I want to know what you thought you were gonna do).
I showed her my scripture, and surprisingly, she was okay with it. She just said, "now when you see 'selah' you just skip that part. You don't say that part okay?" And I remember I kept repeating "skip it?" "Just don't say it at all??" because I was so unsure. LOL.
