Luke 14 - Matthew Henry's Concise Commentary on the Bible

He teaches humility.

Even in the common actions of life, Christ marks what we do, not only in our religious assemblies, but at our tables. We see in many cases, that a man's pride will bring him low, and before honour is humility. Our Saviour here teaches, that works of charity are better than works of show. But our Lord did not mean that a proud and unbelieving liberality should be rewarded, but that his precept of doing good to the poor and afflicted should be observed from love to him.

(Lu 14:15-24)
