Yesterday I was reading through Leviticus and I came across Leviticus chapter 26 verse 27-29 where it says

"And if ye will not for all this hearken unto me, but walk contrary unto me; Then I will walk contrary unto you also in fury; and I, even I, will chastise you seven times for your sins. And ye shall eat the flesh of your sons, and the flesh of your daughters shall ye eat.

Does God order cannibalism in this verse and could someone please explain?
