Swearing in G‑d's Name
"And swear by His Name"—Deuteronomy 10:20.
When necessary to conclusively confirm or deny, we are commanded to swear solely in G‑d's Name. This constitutes an honor for, and exaltation of, G‑d.
It is forbidden to swear in the name of any other entity, such as an angel or constellation, unless the person's intention is only to swear in the name of the one and only Power who created these entities.
