B. Woman  pours myrrh on Jesus, 26:6-7 ( muron , v 7)

C. Disciples complain: give to poor, 26:8-9 ( ptochos , v 9)

D. Jesus: She’s done a good deed, 26:10

C’. Poor always with you, 26:11 ( ptochos , v 11)

B’. Woman poured perfume to prepare for burial, 26:12-13 ( muron , v 12)

A’. Judas and the priests: chief priests, deliver, 26:14-16 ( paradidomi , vv 15, 16; archiereus , v 14)
