Albert Barnes on Luke 14:7

A parable. The word parable, here, means rather a precept, an injunction. He gave a rule or precept about the proper manner of attending a feast, or about the humility which ought to be manifested on such occasions.

That were bidden. That were invited by the Pharisee. It seems that he had invited his friends to dine with him on that day.

When he marked. When he observed or saw.

Chief rooms. The word rooms here does not express the meaning of the original. It does not mean apartments, but the higher places at the table; those which were nearest the head of the table and to him who had invited them. Mt 23:6. That this was the common character of the Pharisees appears from Mt 23:6.
