'Feet' in the Bible

Jehovah is slow to anger, and great in power, And Jehovah doth not entirely acquit, In a hurricane and in a tempest is His way, And a cloud is the dust of His feet.

Lo, on the mountains the feet of one proclaiming tidings, sounding peace! Celebrate, O Judah, thy festivals, complete thy vows, For add no more to pass over into thee doth the worthless, He hath been completely cut off!
