In Hebrew, and ancient Greek as well, the words for foot πούς and hand χείρ originally meant the whole limb, not just the foot and hand; that is, πούς could mean the whole leg, and χείρ the whole upper limb, from the finger tips to the shoulder. In Revelation, we can see that the writer uses these words that way, from Revelation 10:1, where he says (ESV), “Then I saw another mighty angel coming down from heaven, wrapped in a cloud, with a rainbow over his head, and his face was like the sun, and his legs like pillars of fire.”

Certainly, legs are like pillars, and feet are not like pillars. The ESV correctly renders πούς as legs, and not feet. Those translations that render it “feet” are just plain wrong.
