The four blacksmiths (Zech 1:20-1:21)

“Then Yahweh showed me

Four blacksmiths!

I said.

‘What are these coming to do?’

He answered.

‘These are the horns

That scattered Judah.

Thus,

No head could be raised.

But they have come

To terrify them.

They have come

To strike down

The horns

Of the nations

That lifted up

Their horns

Against the land of Judah,

To scatter it.’”

Next Yahweh showed Zechariah 4 blacksmiths.  Of course, Zechariah asked what these blacksmiths were going to do.  The angel that had been talking to Zechariah told him that these blacksmiths had come to scare the 4 horns and strike them down.  Thus, these blacksmiths were agents or angels of Yahweh that had come to protect Judah.  They were going to scatter the other 4 horns, since those horns would be smashed down.
