Their number is mentioned as being many; and many of the Jews had come to Martha and Mary to console them. This was an act of piety: "Rejoice with those who rejoice, weep with those who weep" (Rom 12:15); "Do not fail those who weep, but mourn with those who mourn" (Sir 7:34).

Now many of the Jews had come to Martha and Mary, to console them concerning their brother; because at that time there was much sorrow over the dead, but after the death of Christ there ought to be consolation concerning the good who have died: because "blessed are the dead who die in the Lord"; therefore First Thessalonians chapter four: "We do not want you to be ignorant concerning those who have fallen asleep, so that you may not grieve as do the rest, who have no hope."
