“Yahweh will sit

As a refiner.

Yahweh will sit

As he purifier

Of silver.

He will purify

The descendants of Levi.

He will refine them

Like gold,

Like silver,

Until they present offerings

To Yahweh

In righteousness.

Then the offerings

Of Judah,

The offerings

Of Jerusalem

Will be pleasing

To Yahweh,

As in the days of old,

As in former years.”

Yahweh was going to purify the priests or the descendants of Levi, like people refined gold and silver.  Thus, they would be able to present righteous offerings for Judah and Jerusalem.  Then these offerings would be like the good old days of former years.
