AKRIEL
Akriel is the Angel of barrenness. In Jewish magical lore, Akriel’s name is invoked in prayers for children by repeating Deuteronomy 7:12, which promises fruitfulness of body and materiality in reward for keeping God’s laws.
The invocation of the name enhances the supernatural forces inherent in the biblical verses.
