Yigdal (Hebrew: יִגְדָּל‎; yighdāl, or Hebrew: יִגְדַּל‎; yighdal; means "Magnify [O Living God]") is a Jewish hymn which in various rituals shares with Adon 'Olam the place of honor at the opening of the morning and the close of the evening service. It is based on the 13 Articles of Faith (sometimes referred to as "the 13 Creeds") formulated by Moses ben Maimon, and was written by Daniel ben Judah Dayyan , who spent eight years in improving it, completing it in 1404. This was not the only metrical presentment of the Creeds; but it has outlived all others, whether in Hebrew or in the vernacular. A translation can be found in any bilingual siddur.
