I find it interesting that the verse states "a certain place". Not just - 'he stopped for the night because the sun had set'. A certain place. He had come to a spot where he could safely and comfortably stop his journey and get some rest.
What place? A specific stage along his journey? A place shown to him?
He didn't stop just any random spot. He didn't stop just because he felt tired. He kept going until he reached a "certain place".
1) specific, but not explicitly named or stated
2) known for sure; established beyond doubt
When we come to a "certain" place - we can also find rest.
A place where we are certain where our strength comes from. Certain where our hope lies. Certain we are loved. Certain of grace.
When we are certain of our God and certain who we are in Him. Even when the sun sets. When we are tired and the journey is long.
We can stop and find rest.
