1 Kings 2:40

And Shimei arose, and saddled his ass, and went to Gath to Achish to seek his servants: and Shimei went, and brought his servants from Gath.

Cross-reference

1 Samuel 27:2 shows David also went to Achish king of Gath—Shimei's journey echoes David's, but for different reasons (refuge vs. retrieving servants).
