2 Samuel 2:1-2

So it happened after this that David inquired of the LORD, saying, “Shall I go up into one of the cities of Judah?” And the LORD said to him, “Go up.” David asked, “Where shall I go?” And He said, “To Hebron.” So David went up there [to Hebron] with his two wives also, Ahinoam of Jezreel and Abigail the widow of Nabal of Carmel [in Judah].
