The answer
As mentioned in the passages you provided, Mary (the sister of Lazarus) paid tribute to the Lord before His death with costly fragrant oil as she felt indebted to Him, not knowing how to befittingly honor Him, except with the best that she has. She knew that the Jews were plotting against Him, but was convinced that their evil plots would be fruitless and death would have no power over Christ.Answered by His Eminence Metropolitan Youssef (opens in a new tab)
