The author of this song, traditionally sung during the Shabbat midday meal, is unknown. Some think it may have been Israel ben Moses Najara who was born in Syria about 1555 and served for many years as Rabbi of Gaza. His most famous zemer composition is the well known Yah Ribon which spells out his first name Yisrael in the first letters of successive verses. This is also the case for Yom Ze M'chubad. Other sources believe that it predates Najara.
