But {instead} he will honor the god of fortresses, a god whom his ancestors did not know. He will honor [him] with gold, and with silver, and with precious stones and with costly gifts.

And [while] he was at Bethany in the house of Simon the leper, [as] he was reclining for a meal, a woman came holding an alabaster flask of very costly perfumed oil of genuine nard. [After] breaking the alabaster flask, she poured [it] out on his head.
