Kabbalah sobre Salmos 98:1

Rabbi Yosi began with the verse, "A psalm, O sing (Heb. שִׁירוּ) to Hashem a new song; for He has done marvelous things, His right hand, and His holy arm have gained Him the victory" (Tehilim 98:1). The friends explained that this was said by cows, as it is written, "And the cows took the straight way (Heb. וַיִּשַּׁרְנָה)" (I Samuel 6:12). The word "וַיִּשַּׁרְנָה" also means that they sang (Heb. sharu) a new song. What new song? "A psalm. O sing to Hashem a new song."
