Targum zu Wajikra 26:29

And ye shall eat the flesh of your sons, and the flesh of your daughters. Mosheh the prophet hath said, How heavy will have been the guilt, and how bitter those sins, that caused our fathers to eat the flesh of their sons, and the flesh of their daughters, because they kept not the commandments of the law!

How evil that guilt, and bow bitter those sins, which caused our fathers in Jerusalem to eat the flesh of their sons and their daughters!
