לרצון להם לפני ה׳. "that they may be accepted on their behalf by G'd with goodwill." We need to understand why the two words "Holy unto G'd" possessed the ability to attract G'd's goodwill. Perhaps the word "Holy" referred to the people of Israel. We find Israel described as "Holy" by Jeremiah (Jeremiah 2,3). The word "unto G'd" are meant to convey that the Jewish people as a whole are devoted and dedicated to G'd. This fact (and not merely the words on the ציץ) ensure G'd's goodwill towards the people. This is the mystical dimension of the words אני לדודי ודודי לי, in Song of Songs 6,3. Solomon means that "if I am devoted to G'd, as a result G'd i.e. דודי, will turn His benevolent attention towards me."
