Tobit 4:13

13 So now, my son, love your brethren, and in your heart do not disdain your brethren and the sons and daughters of your people by refusing to take a wife for yourself from among them. For in pride there is ruin and great confusion; and in shiftlessness there is loss and great want, because shiftlessness is the mother of famine.
