Let’s observe how Ehud, whose name means “praise,” discharged his leadership. History teaches us, in its writings about King Eglon, how this most wise Ehud with particular skill and, if I may say, cunning but praiseworthy deception, would kill the tyrant Eglon, whose name means “round” or “circular.” It was necessary, then, to have the quality of judges of our people as was this Ehud, whose name means “praise,” so to cut through all his rolling motion and circuit of evil ways and to destroy the king of the Moabites. But Moabite is translated as “flow” or “effusion.” Who can the ruler or leader of this flowing and dissolute people be seen or understood to be, therefore, other than the word of that philosophy which adjudges pleasure to be the highest good, a philosophy which the word of the gospel, which has been compared to a sword, killed and destroyed? And this prophetic word would become enclosed within their belly and lowest stomach by means of the “ambidextrous” judge’s arguments, to extinguish the Moabites by assertion of the truth, enclosing also every sense of perverse doctrine and dull understanding “which extols itself and rises against the spiritual knowledge of Christ,” so that by acting thus and by doing battle with the word of God, each judge of the church may also become a praising Ehud, about whom the Lord would say, “Well done, good and faithful servant; you have been faithful over a few, so I will set you over many.”
