John Gill Commentary Amos 5:10

"They hate him that reproveth in the gate, and they abhor him that speaketh uprightly." — Amos 5:10 (ASV)

They hate him that rebukes in the gate Openly and publicly in the courts of judicature: wicked judges hated the prophets of the Lord, such as Amos, who faithfully reproved them for the perversion of justice, even when they were upon the bench: or the people were so corrupt and degenerate, that they hated those faithful judges who reproved them for their vices in the open courts of justice, when they came before them, The former sense seems best, and more agreeable to the context:

and they abhor him that speaks uprightly ; not only hate him, but abhor him, cannot bear the sight of him, or to hear his name mentioned that speaks out his mind freely and honestly, and tells them of their sins, and advises them to repent of them, and leave them.
