John 13:33-35

Young's Literal Translation

³³ `Little children, yet a little am I with you; ye will seek me, and, according as I said to the Jews -- Whither I go away, ye are not able to come, to you also I do say [it] now.

³⁴ `A new commandment I give to you, that ye love one another; according as I did love you, that ye also love one another;

³⁵ in this shall all know that ye are my disciples, if ye may have love one to another.'
