Three times in Psalm 46 (vss. 3, 7 & 11) and throughout the Psalms we read this word “selah”.
What each of the Psalmist are encouraging us to do is pause, rest, take a deep breath and contemplate on what they just written.
The contemplation of verse 3 is to remember the Lord is our refuge and fortress.
In verse 7 the contemplation includes the joyful security His followers have when everything seems to be shaking and falling apart around us.
Verse 11 we remember that The Creator God of the universe takes and has a personal interest in us. He’s present with us!
You can add to these items that are on your own list and SELAH!
