Exodus 18:21 - Matthew Poole's English Annotations on the Holy Bible

Able men, Heb. men of might, not for strength of body, but for greatness, resolution, courage, and constancy of mind, which is the best preservative against partiality and corruption in judgment, to which men of little minds, or narrow souls, are easily swayed by fears, or hopes, or gifts. Such as fear God; which will restrain them from all injustice, even when they have ability and opportunity to do wrong so cunningly or powerfully that they may escape the observation and censure of men. Men of truth, or, of faith, or faithful, such as love the truth, and diligently labour to find it out in all causes, and then pass a true and righteous sentence; not at all respecting persons, but only the truth and right of their causes; such as hate lies and slanders, and will severely rebuke and punish them. Hating covetousness: this, though included in the former, is particularly expressed, because gifts and bribes are the great corrupters of judges and judgments.
