Catholic Commentary on Jeremiah 47

“Ah, sword of the LORD, how long till you rest? Return to your sheath; cease and be still.” (Jeremiah 47:6)

Against the Philistines

The word of the LORD concerning the Philistines: see how the waters are rising in the north; they will overflow the land and everything in it. The people will cry out; all who dwell in the land will wail at the sound of the hooves of galloping steeds, at the noise of enemy chariots and the rumble of their wheels. Fathers will not turn to help their children; their hands will hang limp. Gaza will shave her head in mourning; Ashkelon will be silenced. Ah, sword of the LORD, how long till you rest? Return to your sheath; cease and be still. But how can it rest when the LORD has commanded it, when he has ordered it to attack?

The Catechism draws from Jeremiah's question about the sword the principle of prophetic intercession even for the enemies of Israel: the prophet mourns the destruction of those he was sent to warn (CCC 2635).

Living the Word

Brothers and sisters, ah, sword of the LORD, how long till you rest? Even in the oracle against the enemy, Jeremiah asks for the mercy of its ending. The prophetic heart that announces the sword also prays for its sheathing. Proclaim what God commands and pray for the mercy that limits what God permits. Both belong to the prophetic vocation.

Prayer

Lord God, how long till the sword rests? Have mercy on all who suffer the consequences of the judgment. Through Christ our Lord. Amen.

Judgment on the Philistines
(Zephaniah 2:4-7)
This is the word of the LORD that came to Jeremiah the prophet about the Philistines before Pharaoh struck down Gaza. This is what the LORD says:
 
“See how the waters are rising from the north
and becoming an overflowing torrent.
They will overflow the land and its fullness,
the cities and their inhabitants.
The people will cry out,
and all who dwell in the land will wail
at the sound of the galloping hooves of stallions,
the rumbling of chariots,
and the clatter of their wheels.
The fathers will not turn back for their sons;
their hands will hang limp.
 
For the day has come
to destroy all the Philistines,
to cut off from Tyre and Sidon
every remaining ally.
Indeed, the LORD is about to destroy the Philistines,
the remnant from the coasts of Caphtor.* 47:4 That is, Crete
The people of Gaza will shave their heads in mourning;
Ashkelon will be silenced.
O remnant of their valley, 47:5 That is, the Mediterranean coast or plain
how long will you gash yourself?
 
‘Alas, O sword of the LORD,
how long until you rest?
Return to your sheath;
cease and be still!’
 
How can it rest
when the LORD has commanded it?
He has appointed it against Ashkelon
and the shore of its coastland.”
