This link from Chabad.org presents an audio recording of the apex of the Neilah service, the closing service of the day, where, we beg God one last time to accept our repentance and seal us in the Book of Life. The Neila service includes opening prayers, the Amidah and its repetition, Avinu Malkeinu (Our Father, Our King), the following declaration of our faith, the sounding of the Shofar, and some final closing prayers. In the following section of this service, we proclaim God as our God with the repetition of three phrases:

1. "Hear O Israel, the Lord our God, the Lord is One" (x1) – שמע ישראל ה' אלוהנו ה' אחד
2. "Blessed be the name of the glory of His kingdom forever and ever" (x3)  – ברוך שם כבוד מלכותו לעולם ועד
3. "God – He is the only God" (x7) – ה' הוא האלוהים
