Mandaeism

In Mandaeism, uthras (celestial beings) often have the Mandaic term Ziwa / Ziua (, meaning 'Radiance'; Neo-Mandaic pronunciation ) attached after their names, due to their origins from the World of Light. Pairs of uthras also typically have rhyming names. The names can be alliterative (e.g., Adathan and Yadathan), or one name may have an infixed consonant or syllable (e.g., Kapan and Kanpan).

Hibil Ziwa
Sam Ziwa (or Sam Smira Ziwa)
