1 Kings 2:39-41

39Now it happened at the end of three years, that two slaves of Shimei ran away to Achish the son of Maachah, king of Gath. And they told Shimei, saying, “Look, your slaves are in Gath!”

40So Shimei arose, saddled his donkey, and went to Achish at Gath to seek his slaves. And Shimei went and brought his slaves from Gath.

41And Solomon was told that Shimei had gone from Jerusalem to Gath and had come back.
