הַיּ֣וֹם הַזֶּ֡ה יְסַגֶּרְךָ֩ יְהוָ֨ה בְּיָדִ֜י וְהִכִּיתִ֗ךָ וַהֲסִרֹתִ֤י אֶת־רֹֽאשְׁךָ֙ מֵעָלֶ֔יךָ וְנָ֨תַתִּ֜י פֶּ֣גֶר מַחֲנֵ֤ה פְלִשְׁתִּים֙ הַיּ֣וֹם הַזֶּ֔ה לְע֥וֹף הַשָּׁמַ֖יִם וּלְחַיַּ֣ת הָאָ֑רֶץ וְיֵֽדְעוּ֙ כָּל־הָאָ֔רֶץ כִּ֛י יֵ֥שׁ אֱלֹהִ֖ים לְיִשְׂרָאֵֽל׃
This day will the LORD deliver thee into my hand; and I will smite thee, and take thy head from off thee; and I will give the carcasses of the host of the Philistines this day unto the fowls of the air, and to the wild beasts of the earth; that all the earth may know that there is a God in Israel;

Psalms 92,2, "it is good to pay homage to G-d and to sing praises to Your name, most High." This is the conclusion reached by David after having overcome doubts in this matter. Cognition of G-d’s works is our primary task. Glorifying His works in song and music is the natural corollary of such cognition. The song the Jewish people sang after their deliverance from the army of Pharaoh by G-d’s miraculous personal intervention, is a prime example of this.
