Comentario sobre Levítico 19:37

ושמרתם את כל חקותי ואת כל משפטי, study them so that you will become aware of how fair they are.

ושמרתם את כל חקתי, “you are to meticulously observe all My statutes;” this was repeated here once more as it sums up the chapter.

ועשיתם אותם, through your study of both My statutes and My social legislation you will become impressed with their worth so that you will observe them and carry them out as a result of having gained greater insight of their meaning.

'אני ה; the Torah means to remind us that observance of G’d’s laws must be because they are G’d’s laws, i.e. we must not add or detract from the details of these laws in the mistaken belief that we would improve them by our additions or subtractions. Seeing G’d Himself is surely perfect, how could His legislation be any less than perfect?
