To comfort them concerning their brother. This was, no doubt, the object which they had in view, but God had another object to accomplish, as we have stated. It is evident from what is here mentioned, that the house of Lazarus and his sisters was greatly respected and honored. Again, as it is natural that the death of friends should occasion grief and mourning to men, this duty, which the Evangelist mentions, ought not to be blamed, unless on this ground, that sinful excess, which prevails in this and in other departments of life, corrupts what is not in itself sinful.

Many of the Jews - Probably their distant relatives or their friends.
To comfort - These visits of consolation were commonly extended to seven clays (Grotius; Lightfoot).

Many of the Jews came - Bethany being so nigh to Jerusalem, many of the relatives and friends of the family came, according to the Jewish custom, to mourn with the afflicted sisters. Mourning, among the Jews, lasted about thirty days: the three first days were termed days of weeping: then followed seven of lamentation. During the three days, the mourner did no servile work; and, if any one saluted him, he did not return the salutation. During the seven days, he did no servile work, except in private - lay with his bed on the floor - did not put on his sandals - did not wash nor anoint himself - had his head covered - and neither read in the law, the Mishnah, nor the Talmud. All the thirty days he continued unshaven, wore no white or new clothes, and did not sew up the rents which he had made in his garments. See Lightfoot, and see on John 11:31 (note).

(4) And many of the Jews came to Martha and Mary, to comfort them concerning their brother.
(4) God, who is the maker of nature, does not condemn natural emotions, but shows that they ought to be guided by the rule of faith.

And many of the Jews came to Martha and Mary,.... Or "to those that were about Martha and Mary"; in order to have access to them, they came to them, and to the rest of the family; though the phrase may design them only, as the Vulgate Latin, and all the Oriental versions read: these Jews, as appears from the context, John 11:18, came from Jerusalem, and might be some of the principal inhabitants; and it may be concluded, that these persons, Lazarus, Martha, and Mary, were people of note and figure; and indeed all the accounts of them here, and elsewhere, show the same; see Luke 10:38. The end of their coming to them was
to comfort them concerning their brother; by reason of his death, as was usual with the Jews to do, after the dead was buried; for they did not allow of it before: hence that saying (g) of R. Simeon ben Eleazar,
"do not comfort him (thy friend) in the time his dead lies before him.''
The first office of this kind was done when they returned from the grave; for it is said (h), when they return
"from the grave they make rows round about the mourner, "to comfort him", and they make him to sit, and they stand, and there never were less than ten in a row.''
It was an ancient custom for the mourners to stand in their place in a row, and all the people passed by, and every man as he came to the mourner comforted him, and passed on (i). But besides these consolations, there were others administered at their own houses, which were usually done the first week, for it is said (k),
"the mourner the first week does not go out of the door of his house; the second he goes out, but does not sit, or continue in his place; the third he continues in his place, but does not speak; the fourth, lo, he is as every other man. R. Judah says, there is no need to say, the first week he does not go out of the door of his house, for behold, all come to his house, "to comfort him".''
And is was on the third day more particularly on which these consolatory visits were paid (l):
"on the first day he (the mourner) did not wear his phylacteries; on the second, he put them on; on the third day, others come to comfort him.''
This rule the Jews here seem to have observed, since Lazarus had been dead four days; and they were come from Jerusalem hither to comfort his sisters on account of his death. The whole of this ceremony is thus related by Maimonides (m),
"how do they comfort mourners? after they have buried the dead, the mourners gather together, and stand on the side of the grave; and all that accompany the dead stand round about them, one row within another: and there is no row less than ten; and the mourners are not of the number; the mourners stand on the left hand of the comforters; and all the comforters go to the mourners, one by one, and say to them, , "may ye be comforted from heaven": after that the mourner goes to his house, and every day of the seven days of mourning, men come to comfort him; whether new faces come, or do not, the mourner sits down at the head, (or in the chief place,) and no comforters may sit but upon the floor, as it is said, Job 2:13, "and they sat with him on the ground": nor may they say any thing until the mourner has opened his mouth first, as it is said, Job 2:13, "and none spake a word unto him": and it is written afterwards, Job 3:1, "so opened Job his mouth", &c. and Eliphaz answered, Job 4:1, and when he nods with his head, the comforters may not sit with him any longer, that they may not trouble him more than is necessary. If a man dies, and there are no mourners to be comforted, ten worthy men go and sit in his place all the seven days of mourning; and the rest of the people gather to them; and if there are not ten fixed every day, ten of the rest of the people gather together, and sit in his place:''
for this business of comforting mourners was reckoned an act of great piety and mercy (n); and these Jews here might come, not so much out of respect to the dead, or to his sisters, as because it was thought to be a meritorious act.

many of the Jews came to Martha and Mary to comfort them--Thus were provided, in a most natural way, so many witnesses of the glorious miracle that was to follow, as to put the fact beyond possible question.

Many of the Jews came to Martha and Mary. Jews from Jerusalem, of which Bethany was a suburb. As "Jews" in John's usage means the ruling classes, the fact that they came shows that the family of Lazarus was influential. These came to "comfort;" that is, to sit with and talk to the mourners. The mourning was kept up thirty days.
