These are the closing moments of Yom Kippur. 

The apex of the Ne'ilah service, the emotional peak, is when we pronounce, in unison, three verses proclaiming G-d as our G‑d.

We recite the Shema — "Hear O Israel, the Lord our God, the Lord is One." It is written that when we recite this verse, every Jew should have the intention of giving up his or her soul for the sanctification of G‑d's name, and this intention will be considered as if we have indeed withstood the test to sanctify the Divine Name. 

Then we recite the next verse — "Blessed be the name of the glory of His kingdom forever and ever" — three times, together. This is followed by the declaration of G‑d's unity, "G‑d - He is the Only G‑d" — first recited at Mt. Carmel by the prophet Elijah — seven times, in the most ardent way. The shofar is then sounded, one long sound, and the Ne'ilah service ends with the prayer:

"Next Year may we be in Jerusalem!"
