Parshas Emor: Rav Chaim Kanievsky - Rus, Boaz, And Naomi Make An Appearance In Middle Of The Parsha
Parshas Emor discusses the Yomim Tovim starting with Pesach and going chronologically through the year until Succos.  At the end of pasukim discussing Shavuos and the Korban Shtei HaLechem the torah tells of the mitzva of leaving the Pei'a and Leket of the field to the poor.  Not only is this out of place but it was already written in Parshas Kedoshim.  

Rav Chaim Kanievsky says that the torah is hinting to us about Rus who collected Leket from Boaz's field.  Rus first came to his field in the season when they were cutting the barley, which is this time of year.  Some even say they were cutting for the Korban Omer which is discussed in the preceding pasukim.  

Rav Chaim points out that the pasuk says (Emor 23:22), "LeAni V'LaGer Ta'azov", taking the word V'LaGer, the last letter of the preceding word, and the first letter of the subsequent word, it spells Giyores, alluding to Rus.  Additionally the word Ta'azov has the letters of Boaz in it.  The extra letter "Tuf" together with the first and last letters of "V'LaGer" is the word Rus.  The gematria of the words "LeAni V'LaGer Ta'azov Osam" is equal to "Zu Naomi V'Rus HaMoavia Kalasa", this is Naomi and Rus the Moavi her daughter-in-law.
