Melachim Alef 3:6

And Sh'lomo said, Thou hast showed unto Thy eved Dovid Avi chesed gadol (great mercy), according as he walked before Thee in emes, and in tzedakah, and in yesharah levav (uprightness of heart) with Thee; and Thou hast been shomer to preserve this chesed hagadol for him, that Thou hast given him ben to sit on his kisse, as is this day.
