Yochanan 13:33-35 Orthodox Jewish Bible (OJB)
33 Yeladim, yet a little while I am with you; you will seek me, and as I said to those of Yehudah, Where I go away, you are not able to come. Also to you I say this now.
34 A mitzvah chadasha I give to you, that you have ahavah (agape) one for the other, as I have had ahavah (agape) for you, so also you have ahavah (agape) one for the another. [VAYIKRA 19:18]
35 By this will kol Bnei Adam have da’as that my talmidim you are, if ahavah you have one for the other.
