'Feet' in the Bible

The Lord is slow to anger and great in powerAnd He will by no means leave the guilty unpunished.The Lord has His way in the whirlwind and in the storm,And the clouds are the dust beneath His feet.

Behold, on the mountains the feet of him who brings good news [telling of Assyria’s destruction],Who announces peace and prosperity!Celebrate your feasts, O Judah;Perform your vows.For the wicked one [the king of Assyria] will never again pass through you;He is completely cut off.
