Rashi on TanakhPsalms 108

My heart is steadfast faithful with You.

even my glory Even my glory is what I sing to You. Another explanation: Even my glory Even according to my honor, I shall not hesitate to sing to Him, and I shall not take glory for myself.

I shall awaken the dawn It is the custom of other kings that the dawn awakens them, but I awaken the dawn, for I rise at midnight, when the psaltery and the harp awaken me, as our Rabbis said (Ber. 3b): A harp was suspended above David’s bed. As soon as midnight arrived, the north wind would blow on it and it would play by itself.

above the heavens and one verse says (above 57:11): “is up to the heavens.” Our Rabbis explained: This one speaks of those who perform [a commandment] for its sake [i.e., for the sole purpose of obeying the Torah], and that one deals with those who perform [the commandments] with ulterior motives.

and answer me for all Your people and Your beloved ones are dependent upon me.

God spoke with His holiness that I would reign and that the time would come that I would rejoice in His word.

that I would allot a portion I shall divide the land of my enemies to Israel, like (Gen. 48: 22): “one portion (שכם) more than your brethren.”

Moab is my washbasin i.e., my slaves and my servants, like a utensil that people use.

on Edom I shall cast my servitude, that their kings should put my shoes on my feet.

I shall shout I shall raise my voice to them to frighten them.

Who will bring me in the time of the Messiah, to stretch forth my hand upon Esau in his fortified cities? He Who Who led us already upon Edom, that I smote them in the Valley of Salt, eighteen thousand.
