Charles Ellicott Commentary Leviticus 18:4

"Mine ordinances shall ye do, and my statutes shall ye keep, to walk therein: I am Jehovah your God." — Leviticus 18:4 (ASV)

You shall do my judgments. —The expression “my judgments and my ordinances” is here used emphatically, in opposition to “their ordinances,” and has here the force of Mine only; just as the phrase Him you shall serve (Deuteronomy 6:13) is explained by Christ Him only you shall serve (Matthew 4:10).
