may Takeminakata (Suwa) and Hachiman bear witness; samurai vow of truthfulness
Historical samurai oath invoking the deities of Suwa and Hachiman to witness the speaker's sincerity. Used in period contexts; not part of modern everyday speech.
"May Suwa and Hachiman bear witness, I shall never break this promise," the samurai swore.
A set phrase from the samurai era combining the names of two major Shinto deities, Suwa (諏訪) and Hachiman (八幡), with 照覧あれ (may they see and judge). The exact historical origin is uncertain, but it reflects the practice of swearing oaths before gods.
