Mari b. Rahel that ritually slaughtered meat had been salted with trefah meat.7 He came before Raba who sa3 d to him, It is written: The unclean,8 to signify that the juice and the broth and the sediment of these [which are unclean] are forbidden.9 fat can then very easily be poured off into another vessel, and it may be eaten. time to exude the blood and so long as it exudes it will not absorb. ‘unclean’ is superfluous. not absorb blood from the other because each is discharging it, each will however absorb the juice from the other, so that the ritually slaughtered meat would be rendered forbidden on account of the juice of the other.
