Shalt be blessed - Blessed in the "act" of doing good, which furnishes more "happiness" than riches can give, and blessed or rewarded "by God" in the day of judgment.

They cannot recompense thee - They cannot invite you again, and thus pay you; and by inviting "them" you show that you have a "disposition" to do good.

The resurrection of the just - When the just or holy shall be raised from the dead. Then "God" shall reward those who have done good to the poor and needy from love to the Lord Jesus Christ, Matthew 10:42; Matthew 25:34-36.

For they cannot recompense thee - Because you have done it for God's sake only, and they cannot make you a recompense, therefore God will consider himself your debtor, and will recompense you in the resurrection of the righteous. There are many very excellent sayings among the rabbins on the excellence of charity. They produce both Job and Abraham as examples of a very merciful disposition. "Job, say they, had an open door on each of the four quarters of his house, that the poor, from whatever direction they might come, might find the door of hospitality open to receive them. But Abraham was more charitable than Job, for he traveled over the whole land in order to find out the poor, that he might conduct them to his house."

And thou shalt be blessed,.... By God, with an increase of worldly substance, or with spiritual blessings, and with eternal glory and happiness; and by these poor objects, who will pray to God for a blessing upon such a kind benefactor:

for they cannot recompense thee; by inviting again to a like entertainment, as rich guests can do, and when they have done that there is nothing else to be expected; but such that entertain the poor can have no return from them, and yet a retaliation will be made:

for thou shalt be recompensed at the resurrection of the just; when the just shall rise again, which will be the first resurrection; and happy is he that has part in it: for the righteous, or dead in Christ will rise first; and notice will be taken of the good works of the saints, particularly of their acts of beneficence to the poor members of Christ; and which they have done in faith, from a principle of love to Christ, and with a view to the glory of God, and the good of their fellow creatures and Christians.

And thou shalt be blessed; for they cannot recompense thee: for thou shalt be recompensed at the resurrection of the just.

14:12-14 When thou makest a dinner. To give dinners for the sake of earthly reward is worldly; to feed the needy is heavenly, and will be rewarded in heaven.

14:14 One of them that sat at table hearing these things - And being touched therewith, said, Happy is he that shall eat bread in the kingdom of God - Alluding to what had just been spoken. It means, he that shall have a part in the resurrection of the just.

14. blessed-acting from disinterested, god-like compassion for the wretched.

14:7-14 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.
