3 Then Mary took about a pint of expensive perfume, made of pure nard, and she anointed Jesus’ feet and wiped them with her hair. And the house was filled with the fragrance of the perfume. 4 But one of his disciples, Judas Iscariot, who was later to betray him, objected, 5 “Why wasn’t this perfume sold and the money given to the poor? It was worth a year’s wages.
14 Then one of the Twelve—the one called Judas Iscariot—went to the chief priests 15 and asked, “What are you willing to give me if I deliver him over to you?” So they counted out for him thirty pieces of silver. 16 From then on Judas watched for an opportunity to hand him over.
