On the second the [red] cow was burned. Rashi wished to answer this so that you would not ask: Didn’t the Levites begin their service immediately after the erection of the Mishkon as is written shortly? How would they be permitted to do this, since they were impure due to contact with a corpse and could not be purified since the red cow has not yet been burned? One cannot say that the cow was burned before the erection of the Mishkon because concerning its sprinkling in Parshas Chukas (Bamidbar 19:4) the Torah writes “opposite the face of the tent” implying that the Mishkon has already been erected when it was slaughtered. He answers “on the second, the cow was burned…” thus it emerges that they were purified on the seventh.

זאת חקת התורה, “This is the statute of the law of the Torah;” The “statute” referred to here are the laws of ritual defilement and subsequent rites of purification. They were communicated to the people on the first day of Nissan, on the day the Tabernacle was erected ready for service. (Talmud, tractate Gittin folio 60). It had to be communicated on that day, as on the following day the red heifer, the instrument without which purification could not take place, was burned. Without knowledge of these procedures, the Passover, which would be offered on the fourteenth day of that month could not have been offered. The Torah had stipulated in verse 4 of our chapter that the location for the sprinkling of the waters containing the ash of that red heifer was opposite, i.e. facing the Tabernacle. It had to be inserted here as there were people, who as a result of the rebellion of Korach had become ritually contaminated.
Rabbeinu Bahya
A Midrashic approach: The “be holy for I am holy,” with which our portion commences reflects the fact that the concept of a nation such as Israel inspired G’d to create the universe in the first place. Expressed differently: Israel shared G’d’s holiness already before the universe or the people were created. At this time G’d decided that the time had come for the people of Israel to demonstrate this latent holiness in actual visible fashion (compare Tanchuma Kedoshim 2). If we were to illustrate this concept in a parable the matter is similar to a king who has become engaged to a bride, i.e. she has become designated for him exclusively. This prompts the king to say: “seeing that I am the king and you are going to become my queen you ought to share my glory. Seeing that my glory is my title “king,” you ought to share this glory of mine.” Applied to G’d and Israel respectively, G’d’s glory being His being holy, He is now (immediately prior to the revelation at Mount Sinai) desirous of His fiancee the Jewish people sharing this holiness. The way to achieve this is to observe the laws of the Torah, plus. This is precisely what happened prior to the revelation at Mount Sinai when G’d told Moses to “sanctify” the people (Exodus 19,10), whereas G’d Himself sanctified the people when He said: “you will be to Me a kingdom of priests and a holy nation” (Exodus 19,6).
Rabbi Levi (Vayikra Rabbah 24,5) claimed that the entire Ten Commandments are recorded in this portion. Whereas in the Decalogue we read אנכי ה' אלוקיך, “I am the Lord your G’d,” in our portion (19,4) we read אני ה' אלוקיכם. Whereas in the Decalogue we are told לא יהיה לך אלוהים אחרים, “do not have any other gods and do not make yourselves a hewn image, etc.,” we are told here (verse 4) “do not make yourselves a molten image.” Whereas in the Decalogue we are told not to utter the name of the Lord in vain, we are told here not to swear a false oath using the Lord’s name (verse 12). Whereas we are told in the Ten Commandments to observe the Sabbath, we are told here to observe the Lord’s Sabbath days (verse 3). Whereas we are told in the Decalogue to honour father and mother, we are told here to revere mother and father (verse 3). Whereas we are told in the Ten Commandments not to commit murder, we are told here “not to stand idly by when we see someone being murdered.” (19,16). In the Ten Commandments we are told not to commit adultery, whereas in our portion here we are being told: “do not desecrate your daughter to make her a harlot” (verse 29). The Decalogue commands us not to steal, whereas here we are told: “do not steal” (19,11). In the Decalogue the Torah warns against bearing false witness against someone, whereas in our portion we are warned: “do not commit character assassination, defamation” (19,16). In the Decalogue we are exhorted not to covet other people’s possessions, especially his wife, whereas here the Torah commands us to: “love what is your neighbor's just as what is yours,” i.e. not to covet what is his” (19,18).
