'Dinner' in the Bible

Now after Jesus had spoken, a Pharisee asked Him to have lunch with him. He went in [the Pharisee’s home] and reclined at the table [without ceremonially washing His hands].

The Pharisee noticed this and was surprised that Jesus did not first ceremonially wash before the meal.

Jesus also went on to say to the one who had invited Him, “When you give a luncheon or a dinner, do not invite your friends or your brothers or your relatives or wealthy neighbors, otherwise they may also invite you in return and that will be your repayment.
