Matthew 17:3

The Greek phrase "ὤφθη αὐτοῖς" (ōphthē autois) translates literally to "he/she/it was seen by them" in English. The Greek word "ὤφθη" (ophthē) is a verb that means "he/she/it was seen" or "appeared." It is a third person singular aorist passive indicative form of the verb "ὁράω" (horáō), which means "to see" or "to perceive." In biblical contexts, particularly in the New Testament, ὤφθη is often used to describe appearances or manifestations of divine or supernatural beings, such as angels or Jesus.

Because it is not plural, ὤφθη cannot grammatically refer to "Moses and Elijah."
