cast the dust # 12_2KI_23_12 # And the altars that [were] on the top of the upper chamber of Ahaz, which the kings of Judah had made, and the altars which Manasseh had made in the two courts of the house of the LORD, did the king beat down, and brake [them] down from thence, and cast the dust of them into the brook Kidron. 
cast the dust # 05_DEU_09_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.
