In Luke 7, a sinful woman wet Jesus' feet with her tears in whose house?

Answer: Simon the Pharisee

Jesus was dining with a Pharisee named Simon when the woman anointed his feet; Jesus then told Simon a parable.

“Then one of the Pharisees invited Jesus to eat with him, and He entered the Pharisee’s house and reclined at the table.”— Luke 7:36 (BSB)
