Albert Barnes Commentary Isaiah 32:5

"The fool shall be no more called noble, nor the churl said to be bountiful." — Isaiah 32:5 (ASV)

The vile person - In Hebrew, ‘Fool.’ However, the context requires us to understand this term as the opposite of liberal. It signifies a person who is stingy, miserly, narrow-minded, and covetous. Such a person is very appropriately designated as a fool.

Shall be no more called liberal - It is probable that under the reign of former princes, when all views of right and wrong had been perverted, unprincipled people were subjected to flattery, and virtues were attributed to them by their friends and admirers. However, this would not be the case under the virtuous reign of the prince celebrated here. Things would be called by their proper names, and flattery would not be permitted to attribute to people qualities that they did not possess.

Nor the churl - The word ‘churl’ properly means a rude, surly, ill-bred man, and then a miser or a stingy person. The Hebrew word properly means a deceiver, a fraudulent man (Gesenius). The word avaricious, however, seems to suit the context. Lowth renders it ‘miser.’ Noyes, ‘crafty.’

Bountiful - Flattery will no longer ascribe to a miserly man a character that does not belong to him.
