Musar על שמואל א 2:7

What cause does one have for pride? Perhaps his wealth? "The Lord impoverishes and enriches" (I Samuel 2:7). Perhaps his honor? It belongs to God, as it is written (I Chronicles 29:12), "Wealth and honor come from You." So how could one adorn himself with G-d's honor? And one who prides himself in his wisdom surely knows that God "takes away the speech of assured men and reasoning from the sages" (Job 12:20). Thus, all are equal before God, since with His anger He lowers the proud and when He wishes He raises the low. So humble yourself and G-d will raise you up!
