John Lightfoot on John 14:16

[He shall give you another Comforter.] I. Amongst all the names and titles given to the Messiah in the Jewish writers, that of Menahem, or the Comforter, hath chiefly obtained; and the days of the Messiah amongst them are styled the days of 'consolation.' The names of Messiah are reckoned up, viz. Shiloh, Jinnon, Chaninah, Menahem. And in Jerusalem Berac. we are told how the Messiah had been born in Bethlehem under the name of Menahem.

Luke 2:25; "Waiting for the consolation of Israel." Targumist upon Jeremiah 31:6: "Those that desire or long for the years of consolation to come." This they were wont to swear by, viz. the desire they had of seeing this consolation. So let me see the consolation.

Now, therefore, bring these words of our Saviour to what hath been said: q.d. "You expect, with the rest of this nation, the consolation in the Messiah and in his presence. Well; I must depart, and withdraw my presence from you; but I will send you in my stead 'another Comforter.'"

II. The minds of the disciples at present were greatly distressed and troubled, so that the promise of a Comforter seems more suitable than that of an Advocate, to their present state and circumstances.
