> While Jesus was in Bethany in the home of Simon the Leper, a woman came to him with an alabaster jar of very expensive perfume, which she poured on his head as he was reclining at the table. When the disciples saw this, they were indignant. "Why this waste?" they asked. "This perfume could have been sold at a high price and the money given to the poor." Aware of this, Jesus said to them, "Why are you bothering this woman? She has done a beautiful thing to me. The poor you will always have with you, but you will not always have me. When she poured this perfume on my body, she did it to prepare me for burial. Truly I tell you, wherever this gospel is preached throughout the world, what she has done will also be told, in memory of her."
Hearing the story as a kid though, I kind of suspected it was really just Jesus saying: "I'm literally about to die for you assholes ffs, can you guys lay off for 5 minutes and just let me have this one nice thing!"
A jewel encrusted prayer book is basically "Tell me you're a hypocrite without telling me you're a hypocrite"
2) observe them intensely.
Can't be gouging up the gift. The friend would get upset.
Maybe a powerful friend. A patron.
Gotta keep the gift nice to stay in good graces.
Maybe it was part of his costume. Something to wag and fondle at aristocratic gatherings.
Appearances are important.
