Az Yeranen - Then the Trees of the Forests Will Sing

 A piyyut, a traditional liturgical song in Hebrew, for Tu Bshvat, the Jewish holiday of trees .

The piyyut was composed by the Ben Ish Chai (Rabbi Yosef Chaim, 1832-1909), the great Baghdadi spiritual leader and scholar, and sung by Rabbi David Menachem.  Thanks to Ezra Orlofsky, who works at a hydrogeochemistry lab in Israel, for sending this in. It would make a beautiful shabbat song.

The first stanza:

Then the trees of the forests will sing

Before God, the mightiest of the mighty,

Arousing melodies and songs

I will sing a new song.
