We see this modeled extensively by Jesus in the Sermon on the Mount. In his series of “you have heard it said…but I say…” he models the institution of making fences around Torah. The letter of Torah says, “Do not commit adultery.” The spirit of the Torah says, “More than avoiding the physical act of adultery, do not even let your mind entertain lustful thoughts which cannot and should not be fulfilled.” In making this declaration, Jesus is making a fence around Torah to ensure that his disciples do not violate Torah by merely obeying the literal understanding of the commandments, rather than the Spirit by which they were given. The Spirit of the Torah assumes and includes the Letter of the Torah, but goes above and beyond it. Let us keep the Spirit of the Torah, by protecting it and “building fences” around it just as our Master.
