Deuteronomy 9:21; Deuteronomy 28:24

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.
24 The LORD shall make the rain of thy land powder and dust: from heaven shall it come down upon thee, until thou be destroyed .
