Leonard, "Selah" means to meditate on this. I was in agreement with what Captboat used as his 6 words. I wrote "Amen" 5 times and then the word "Selah" as my 6th word.
Captboad answered "I sought the Lord....He answered". In other words, Amen means agreement and Selah means meditate on what Captboat said. Selah is mentioned several times in the Psalms.

I hope this answers your question. Selah is mentioned 74 times in the Bible. 71 times in
the Psalms and 3 times in the book of Habakkuk.

Have a blessed day Leonard. Blessings.....
