Proverbs 21:22 tells us that a wise man scales the wall of the mighty and tears down the stronghold in which they trust. 

A stronghold, in this sense, is any territory in which Satan has control. 

A wise man (those who have knowledge and understanding) does two things: 

He scales. 

He tears down. 

He knows how to get up and over the wall (he uses his talent and skill). 

His mission is to tear down the stronghold (he uses his strength). 

Here in Judges 3 we see Eglon doing just that. 

The Moabites were ravishing the Israelites, and something needed to be done. 

Ehud came up with a plan - it was two-fold, just like Proverbs 21 says. 

Vs 15-23 

Ehud “scaled” by offering a gift to the king. 

This is how he got into the king’s good graces.  

But Ehud’s goal wasn’t to stay there and becomes buddies with the ruler. 

His goal was to take him out!  

That’s the second step - he killed the king!  

And in so doing, he tore down the stronghold that was keeping Israel enslaved.  

Too many people today are buddying up with the enemy (scaling the wall) but they have no intention on tearing down the stronghold the enemy represents. 

Ehud shows us a better way, and how he was rewarded with a position of leadership (vs 28) as a result.
