Let the heavens listen (lit. “give ear”) and I will speak, and the land will hear that which I say (lit. “the words of my mouth”). | Haazinu hashamayim va-adabeira, vetishma ha-aretz imrei fi. | הַאֲזִינוּ הַשָּׁמַיִם וַאֲדַבֵּרָה וְתִשְׁמַע הָאָרֶץ אִמְרֵי־פִי׃ |
Torah Thoughts
The word shir means both poem and song in Hebrew. Parashat Ha’azinu is a poem/song, and if you look at the actual text in both a Torah scroll and in your Chumash you will see this reflected.
In Parashat Ha’azinu, Moshe recites (probably chants/sings, as we do today) to all of Israel a poem/song, as he was instructed to do b G-d.
