The phrase "wast consequent on" is not commonly used in modern English, but it was frequently used in older texts. The spelling of this phrase can be explained using IPA phonetic transcription. "Wast" is pronounced /wɑst/ and is the archaic second person singular past tense of "be". "Consequent" is pronounced /ˈkɑnsikwənt/ and means "following as a result". "On" is pronounced /ɑn/ and means "in contact with" or "supporting". Therefore, "wast consequent on" means "you were following as a result of being in contact with".
