2 Samuel 22:32–43 (ESV)

            “For who is God, but the LORD?
                        And who is a rock, except our God?
            This God is my strong refuge
                        and has made my way blameless.
            He made my feet like the feet of a deer
                        and set me secure on the heights.
            He trains my hands for war,
                        so that my arms can bend a bow of bronze.
            You have given me the shield of your salvation,
                        and your gentleness made me great.
            You gave a wide place for my steps under me,
                        and my feet did not slip;
            I pursued my enemies and destroyed them,
                        and did not turn back until they were consumed.
            I consumed them; I thrust them through, so that they did not rise;
                        they fell under my feet.
            For you equipped me with strength for the battle;
                        you made those who rise against me sink under me.
            You made my enemies turn their backs to me,
                        those who hated me, and I destroyed them.
            They looked, but there was none to save;
                        they cried to the LORD, but he did not answer them.
            I beat them fine as the dust of the earth;
                        I crushed them and stamped them down like the mire of the streets.”

This passage starts off with a strong statement of monotheism. The LORD (יְהוָ֑ה, Yahweh) isn’t merely the most powerful God; He’s the only God. That’s what the first commandment is driving at.

“You shall have no other gods before me.” — Exodus 20:3 (ESV)

 The Hebrew that’s translated as, “before me” (עַל־פָּנָֽ֗יַ, al pe-na-ya) is literally, “upon my face.”

Then David completes his point about righteousness by faith.

It was God who has made my way blameless.

It was God that made him capable—even to bend a bow of bronze (which would be impossible). The LORD did it all. He made David strong and He made his enemies weak. The result was total victory.

I beat them fine as the dust of the earth;
            I crushed them and stamped them down like the mire of the streets.
