A.T. Robertson Commentary Luke 14:15

"And when one of them that sat at meat with him heard these things, he said unto him, Blessed is he that shall eat bread in the kingdom of God." — Luke 14:15 (ASV)

Blessed (μακαριος). Happy, same word in the Beatitudes of Jesus (Matthew 5:3ff.). This pious platitude whether due to ignorance or hypocrisy was called forth by Christ's words about the resurrection. It was a common figure among the rabbis, the use of a banquet for the bliss of heaven. This man may mean that this is a prerogative of the Pharisees. He assumed complacently that he will be among the number of the blest. Jesus himself uses this same figure of the spiritual banquet for heavenly bliss (Luke 22:29).

Shall eat (φαγετα). Future middle from εσθιω, defective verb, from stem of the aorist (εφαγον) like εδομα of the old Greek.
