Charles Ellicott Commentary Ezekiel 6:11

"Thus saith the Lord Jehovah: Smite with thy hand, and stamp with thy foot, and say, Alas! because of all the evil abominations of the house of Israel; for they shall fall by the sword, by the famine, and by the pestilence." — Ezekiel 6:11 (ASV)

Smite with thine hand, and stamp with thy foot. —The prophecy returns again to its heavy messages of woe. To clap the hands and stamp the feet, either singly (Numbers 24:10; Ezekiel 21:14; Ezekiel 21:17; Ezekiel 22:13) or together (Ezekiel 25:6), is a gesture of strong emotion or earnestness of purpose. The prophet is here directed to use it as indicating God’s unchangeable determination united to a sense of grievous wrong.
