Chasidut su Salmi 98:6

With trumpets and the voice of the Shofar, sound out before Adonai the King (Psalms 98:6). Let us explain in the manner of parable and metaphor - that of a moral king who traveled to a great forest to amuse himself in hunting animals and birds. He came to a valley in the forest and couldn't find the path straight, true path of the king to return home. He saw villagers in the forest and asked them about the path but they didn't recognize the king and they don't know how to answer him. Because they'd never known the straight, true path of the king! Finally, he found a wise and understanding man and asked him about the path. The wise man understood that this was the king and he became shocked and drew back. He heard him and immediately showed him the path, because in his great wisdom he knew the straight, true path of the king, and he took the king to his palace and sat him down upon his throne. He found favor in the eyes of the king, who lifted him up among the ministers of the kingdom, and dressed him in fine clothing, and appointed him to his treasury. After some time, the man sinned against the king and the king became angry and ordered the highest ministers in the kingdom to judge the man according to his transgressions against the king's commandments. The man suffered much because he knew the judgement would go extremely bad for him, according to the manner that he had sinned against the king. He threw himself down before the king and begged for his life and implored him that before the verdict was passed that he might grant a request in one matter: to dress him in his original clothes that he was wearing at the time he took the king from the woods. The king agreed to do so. And so it was that when he dressed the man in those clothes, the king remembered the great kindness the man did did for him in returning him to his palace and sitting him on his throne. His compassion was stirred and he forgave the sin against him and restored the man to his place. Now this has been a parable: so too with us, the people of the House of Israel - that at the time of the giving of the Torah, the Holy Blessed One offered every nation in every language that they might accept the Torah, but they did not want it. But us, the people of the House of Israel, accepted the Torah with great joy and gladness, and we preceded understanding with action. We accepted upon ourselves the yoke of Heavenly Rule and made it our King over us and accepted God's commandments and holy Torah. And now we have trespassed and rebelled against God. And on Rosh Hashanah, we are afraid of the day of judgement, of the hidden verdict against each person according to their deeds. Therefore, we sound the shofar and dress in the clothes we wore at the time of the giving of the Torah, when we accepted the Torah and raised God as our King with the shofar, as it is written, "the voice of the shofar grew louder," (Exodus 19:19). This is in order that God will remember us according to that merit and forgive us our sins and trespasses and exempt us from judgement and write us for a long, good life, amen, may it be God's will.
