Five massacres, a wedding, and some God-proof iron chariots

This is a hodgepodge of killings from the rest of Judges 1.

After the Jerusalem Massacre (42), the "children of Judah" go on a God-assisted smiting spree, wiping out a bunch of kingdoms "with the edge of the sword."

It's hard to say how many cities were massacred. But there were at least five: three in Hebron, one in Zephath and Bethel.

Judah went against the Canaanites that dwelt in Hebron ... and they slew Sheshai, and Ahiman, and Talmai. Judges Judges 1:10

Judah went with Simeon his brother, and they slew the Canaanites that inhabited Zephath, and utterly destroyed it. 1:17

They also went up against Bethel: and the LORD was with them ... And the spies saw a man come forth out of the city, and they said unto him, Shew us, we pray thee, the entrance into the city, and we will shew thee mercy. And when he shewed them the entrance into the city, they smote the city with the edge of the sword; but they let go the man and all his family. 1:22-25

And there would have been a lot more if it weren't for those damned iron chariots. Some things are just too hard, even for God.

The LORD was with Judah; and he drave out the inhabitants of the mountain; but could not drive out the inhabitants of the valley, because they had chariots of iron. 1:19

Since five cities were massacred, I gave it the usual 1000 per city for a total of 5000.
