In all the judgments against the enemies of Judah we have this verse.

Jer 48:10
"A curse on him who is lax in doing the LORD's work! A curse on him who keeps his sword from bloodshed!

A curse, you say? Oops. Makes us want to not be lax in doing the Lord’s work, whatever that may be.

Many times in Scripture, the sword is used figuratively for the Word of God. When we use the sword (the Word of God) properly, sins are amputated (ouch), often causing trauma, which can only be relieved by submitting to...the Word of God and His authority.

Heb 4:12
For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.

In chapter 8, Jeremiah relates that the people of Moab have shaved their heads, cut off beards, covered with sackcloth...all the customary signs of repentance. But were they truly repentant or were they just in mourning and depressed about their situation?

As God pronounces judgment on Moab and Ammon, He ends with saying He will restore their fortunes. What's this about? Didn't they deserve all the judgments? Uh, oh...I sound a bit like Jonah. However, on Edom, He didn't say He would restore their fortunes. Bozrah is mentioned. It was the capital of Edom, homeland of Jacob's twin brother Esau.

Interestingly, Moab, Edom, and Ammon will be places of safety during the wrath of God in the last days.
