Mischna zu Bereschit 14:22

Whoever possesses these three things, he is of the disciples of Abraham, our father; and [whoever possesses] three other things, he is of the disciples of Balaam, the wicked. A good eye, a humble spirit and a moderate appetite he is of the disciples of Abraham, our father. An evil eye, a haughty spirit and a limitless appetite he is of the disciples of Balaam, the wicked. What is the difference between the disciples of Abraham, our father, and the disciples of Balaam, the wicked? The disciples of Abraham, our father, enjoy this world, and inherit the world to come, as it is said: “I will endow those who love me with substance, I will fill their treasuries” (Proverbs 8:21). But the disciples of Balaam, the wicked, inherit gehinnom, and descend into the nethermost pit, as it is said: “For you, O God, will bring them down to the nethermost pit those murderous and treacherous men; they shall not live out half their days; but I trust in You” (Psalms 55:24).
