The Evangelist referenced Lazarus to emphasize either his restored health or the significance attributed to one who had returned from the dead.
As one of Lazarus's sisters attended to the Lord by serving the meal, the other sister, Mary, perhaps feeling regret for not having expressed her gratitude sooner for her brother's resurrection due to Jesus's swift departure from Bethany, sought to honor Him now. It was customary for Jews to wash the feet of their guests before a meal and to anoint their heads and feet with fragrant oil. Mary intended to perform this act of devotion out of respect for her Savior. Without considering the cost, she brought forth a flask of pure and expensive nard and poured it over Jesus's head and feet, wiping them with her hair, a gesture that symbolized her humility before Him.
Not all perceived this act in the same light. Some of the disciples believed that the nard could have been sold and the proceeds given to the poor. Their recent encounter with Zacchaeus, along with their ongoing commitment to assist those in need, fueled this sentiment. However, one disciple had ulterior motives. He, responsible for the group's finances, envisioned using the money for personal gain under the guise of charity. The concern for the poor was merely a façade for his true intentions. Yet, the Lord defended Mary, countering the seemingly valid argument of His disciples. He sought to remind them of His impending departure, stating that the poor would always be present, but He would not always remain with them. He regarded Mary’s anointing as a significant act in preparation for His burial, asserting that when it comes to burial, no expense is too great, just as no formality should be spared in honor of Him.
