I'd sit on the couch, watching a TV show, and my eyes would grow so heavy. I'd try my hardest to stay awake, but as the clock crept closer toward midnight, most of the time my eyes would doze. I couldn't help it. The later it got the more sleepy I'd get. It was like the painful sleepy if you know what I mean.
I remember always feeling terribly guilty if I nodded off because I was the one in charge of watching the kids. Even though they were in bed peacefully sleeping, no matter how late it was, I felt it was my job to stay awake. And then, every once in awhile, I'd nod off on the couch.
He who keeps you will not slumber.
He doesn't sleep and He doesn't slumber.
We all get in bed at night and go to sleep. We also all occasionally slumber. To slumber is also to sleep, but more specifically it is to sleep lightly or doze.
He who keeps you will neither slumber or sleep.
The Lord is your keeper.
You have a keeper and a helper and He is always watching and ready to help.
