The correct spelling of the phrase "wast elevated" is actually "wert elevated." In Old English, "wert" was the second person singular past tense form of "be," meaning "you were." The "s" in "wast" was added in later Middle English as a sign of grammatical agreement with the subject "thou," but by Early Modern English, "wert" had become the standard form. The pronunciation is /wərt ˈɛləveɪtɪd/, with stress on the second syllable of "elevated."
