In the song Yom Shabbaton it says:
וּפָתְחוּ וְעָנוּ יְיָ אֶחָד
Translated as: They opened and answered G-d is one
The song implies that at some point we answered Hashem is one and the song would seem to imply this was at Har Sinai based on the previous word of the song נַעֲשֶׂה וְנִשְׁמַע אָמְרוּ כְּאֶחָד is there any record of such an issuance from the people of Israel?
