According to Luzzatto, Daniel ben Judah was the author of the well-known hymn Yigdal Elohim Hai containing the thirteen articles of belief of Maimonides.
It is probable that Bedersi wrote a supercommentary on the commentary on Genesis by Abraham ibn Ezra (compare Steinschneider, Cat. Bodl. col. 1283), and that he was the author of the philosophical poem on the thirteen articles of belief of Maimonides (compare Luzzatto, Ḥotam Toknit, p. 2).
The cantor of the Sephardic synagogue in Amsterdam, Hillel, worked with Luzzatto to set several of his poems to music.
