NET

21 As for your sinful thing that you had made, the calf, I took it, melted it down, ground it up until it was as fine as dust, and tossed the dust into the stream that flows down the mountain.

Darby

21 And I took your sin, the calf which ye had made, and burned it with fire, and crushed it, and ground it very small, until it became fine dust; and I cast the dust thereof into the brook that flowed down from the mountain.

KJV

21 And I took your sin, the calf which ye had made, and burnt it with fire, and stamped it, [and] ground [it] very small, [even] until it was as small as dust: and I cast the dust thereof into the brook that descended out of the mount.
