Jeremiah 18:3

Then I went down to the potter's house, and, behold, he wrought a work on the wheels.

Then I went down to the potter's house, and, behold, he was making a work on the wheels.

Then I went down to the potter's house, and, behold, he was making a work on the wheels.

and I go down `to' the potter's house, and lo, he is doing a work on the stones,

So I went down to the potter’s house and saw him working at the wheel.
