I Kings 3:4-10 NKJV
Now the king went to Gibeon to sacrifice there, for that was the great high place: Solomon offered a thousand burnt offerings on that altar. At Gibeon the LORD appeared to Solomon in a dream by night; and God said, “Ask! What shall I give you?”
And Solomon said: “You have shown great mercy to Your servant David my father, because he walked before You in truth, in righteousness, and in uprightness of heart with You; You have continued this great kindness for him, and You have given him a son to sit on his throne, as it is this day. Now, O LORD my God, You have made Your servant king instead of my father David, but I am a little child; I do not know how to go out or come in. And Your servant is in the midst of Your people whom You have chosen, a great people, too numerous to be numbered or counted. Therefore give to Your servant an understanding heart to judge Your people, that I may discern between good and evil. For who is able to judge this great people of Yours?”
The speech pleased the Lord, that Solomon had asked this thing.
