John 13:33,34

Little children An expression intended to signify both their weakness and his tenderness and compassion; as if he had said, Ye whom I love with parental tenderness, and whom my heart pities under all your trials and sorrows; yet a little while, &c. That is, It is but a very little while longer that I am to continue with you: a few hours more will part us; and ye shall seek me Shall wish for my presence and converse when I am gone; and as I said to the Jews, (see John 7:34; John 8:21,) Whither I go ye cannot come Not yet, being not yet prepared for it. A new commandment As if he had said, But observe my parting words, and let them be written on your very hearts; for I give you what I may properly call a new commandment, enjoining a higher degree of mutual love than has generally been possessed and manifested among pious people to each other; a command which I press upon you by new motives, and a new example, and which from henceforth I would have you to consider as confirmed by a new sanction, and to keep ever fresh in your memories. The expression, which, says Dr. Doddridge, “signifies much more than merely a renewed command, is a strong and lively intimation, that the engagements to mutual love, peculiar in the Christian dispensation, are so singular and so cogent, that all other men, when compared with its votaries, may seem uninstructed in the school of friendship, and Jesus may appear, as it were, the first professor of that divine science.” “He called this a new commandment,” observes Dr. Macknight, “not because mutual love had never been enjoined on mankind before, but because it was a precept of peculiar excellence, for the word new in the Hebrew language [often] denotes excellence and truth, as appears from Psalms 33:3; Mark 1:27; Revelation 2:17; and because they were to exercise it under a new relation, according to a new measure, and from new motives. They were to love one another in the relation of his disciples, and with that degree of love which he had shown to them, for they were to lay down their lives for the brethren, 1 John 3:16. Withal they were to love from the consideration of his love, and in order to prove themselves his genuine disciples, by the warmth of their mutual affection.” So also Dr. Campbell: “Our Lord, by this, warns his disciples against taking for their model any example of affection whereunto the age could furnish them; or, indeed, any example less than the love which he all along, especially in his death, manifested for them.”
