Commentary for Psalms 3:2

Great men rise up against me Men great in Torah, great in wisdom, great in wealth, tall in stature, such as Saul; the children of Raphah; Doeg, and Ahitophel.

Lord, how are mine adversaries increased! – For even his son had turned against him for an enemy, and Amasa, his sister's son, was with Absalom, and the greater part of Israel, whose heart inclined after Absalom; and this is reason for the repetition.

Many they are that are rising up against me: – All were rising up against him and were taking counsel to fight against him; and Shimei ben Gera even, who dared to reproach him and to pelt him with stones.
