Matthew Henry's Commentary on Judges 8:3
Commentary on Judges 8:1-3
(Read Judges 8:1-3)
Those who will not attempt or venture any thing in the cause of God, will be the most ready to censure and quarrel with such as are of a more zealous and enterprising spirit. And those who are the most backward to difficult services, will be the most angry not to have the credit of them. Gideon stands here as a great example of self-denial; and shows us that envy is best removed by humility. The Ephraimites had given vent to their passion in very wrong freedom of speech, a certain sign of a weak cause: reason runs low when chiding flies high.
