300px|thumb|right|A medieval silver cross pendant inscribed with the letters AG LA AGLA () is a magic word that appears in some charms. Its meaning is unsettled, but is widely reputed to be a noṭariqōn or kabbalistic acronym for , "Thou, O Lord, art mighty forever", a phrase from Gevurot, the second blessing of the Amidah, the central Jewish prayer. However, according to Katelyn Mesler, "after much searching, I have yet to find evidence of such an interpretation prior to the late fourteenth or fifteenth century, a couple centuries after AGLA begins appearing in magical writings."
