And I will pray the Father. — Comp. Note on John 16:26. The pronoun is again emphatic — “I have given you your part to do. I on My part will pray the Father.” The word used for “pray” is one which implies more of nearness of approach and of familiarity than that which is rendered “ask” in John 14:14. It is the word which John regularly uses when he speaks of our Lord as praying to the Father, and occurs again in John 16:26; John 17:9; John 17:15; John 17:20. The distinction is important, but it has sometimes, perhaps, been unduly pressed. Both words occur in 1 John 5:16. (See Note there.)
And he shall give you another Comforter. — The better rendering is probably another Advocate. The word is used of the third person in the Holy Trinity here, and in John 14:26, and in John 15:26 and John 16:7. In each of these instances it is used by our Lord. It is found once again in the New Testament, and is there applied by St. John to our Lord Himself (1 John 2:1). In the Gospel the English version uniformly translates it by “Comforter.” “In the Epistle it is rendered by “Advocate.” But the whole question is of so much interest and importance that it will be convenient to deal with it in a separate Note. (Comp. Excursus G: The Meaning of the word Paraclete.) The word “another” should be observed as implying that which the Epistle states — the advocacy of the second Person in the Trinity, as well as that of the third.
That he may abide with you for ever. — The thought of the permanent abiding is opposed to the separation which is about to take place between them and the person of our Lord. He would come again to them in the person of the Paraclete, whom He would send to them (John 14:18), and this spiritual presence should remain with them for ever. (Comp. Note on Matthew 28:20.)
