Is My Phylactery Showing?

I'm in the middle of the rhetorical analysis for my thesis of the passage from Luke 6 commonly know as the Sermon on the Plain. (I use the term "commonly" since it's apparent that it's only commonly called that among scripture scholars.) I'm looking at a particular transition, and people commonly note that this transition is a bit odd, but they don't seem to go much further with it. It occurs after the last of the woes and at the beginning of the teaching on love:

“Woe to you, when all men speak well of you, for so their fathers did to the false prophets.

“But I say to you that hear, Love your enemies, do good to those who hate you, bless those who curse you, pray for those who abuse you.
