110 Grk “And Mary.” Here καί (kai) has not been translated because of differences between Greek and English style.
111 Grk “have not known.” The expression in the Greek text is a euphemism for sexual relations. Mary seems to have sensed that the declaration had an element of immediacy to it that excluded Joseph. Many modern translations render this phrase “since I am a virgin,” but the Greek word for virgin is not used in the text, and the euphemistic expression is really more explicit, referring specifically to sexual relations.
