דברים לב ,א: הַאֲזִּינו הַש ָמַיִּם וַאֲדַב ֵׁרָ ה וְתִּש ְמַע הָאָרֶ ץ אִּמְרֵׁ י-פִּי:
Baal HaTurim remarks that this Pasuk begins with the letter ה and ends with the letter י , for Moshe included the name of HaShem at the beginning of the song.
This particular phenomenon occurs 12 times in the Torah.
Further, since the song is arranged “brick by brick and half-brick by half-brick” each line of the song is arranged into three sections, the verse into two parts on the right and the left and the middle section left blank. This, this Pasuk is divided into two sections with the first section הַאֲזִּינוּ הַש מַיִּם וַאֲדַבֵר ה beginning and ending with the letter ה, and the second section וְתִּשְמַע ה א ר ץ אִּמְרֵי-פִּי beginning with the letter ו and ending with the letter י and thus having all four letters of the Divine name.
