My servants shalt eat, but ye shall be hungry - Rabbi Joachan ben Zachai said in a parable: There was a king who invited his servants, but set them no time to come to the feast. The prudent and wary who were among them adorned themselves; and, standing at the gate of the king's house, said, Is there any thing lacking in the king's house? i.e., Is there any work to be done in it? But the foolish which were among them went, and mocking said, When shall the feast be, in which there is no labor? Suddenly, the king sought out his servants: they who were adorned entered in, and they who were still polluted entered in also. The king was glad when he met the prudent, but he was angry when he met the foolish. Therefore he said, Let those sit down, and let them eat; but let these stand and look on.
This parable is very like that of the wise and foolish virgins, Matthew 25, and that of the marriage of the king's son, Matthew 22.
Therefore, thus saith the Lord God - The design of this verse is to show what would be the difference between those who kept and those who forsook his commandments. The one would be objects of his favor, and have abundance; the other would be objects of his displeasure, and be subjected to the evils of poverty, grief, and want.
My servants shall eat - Shall have abundance. They shall be objects of my favor.
But ye - Ye who revolt from me, and who worship idols.
Shall be hungry - Shall be subjected to the evils of want. The idea is, that the one should partake of his favor; the other should be punished.
