ציטירנדיקער פּירוש אויף יחזקאל 1:7

and with two he would cover his feet for modesty, so as not to bare his entire body before his Creator. And in Tanhuma (Emor 8), I saw that the feet were covered because they are like the sole of the foot of a calf, in order not to remind Israel of the sin of the golden calf.

like...copper Like the shine of the Living Beings (above 1:7): “and they sparkled like the color of burnished copper.”

We also have a statement in Midrash Eicha (Eicha Rabba 2:3) in which the time when the guilt of the sin of the golden calf expired is discussed. One scholar said that it expired at the time when King Jerobam made new golden calves which he placed on the road to Jerusalem. He based this on this verse in Ezekiel. Another sage, Rabbi Shmuel bar Nachmeni said that hat the remnants of the guilt of that sin did not become wiped out until the Temple was destroyed. Even though it was no longer subject to retribution, G’d did continue to mention it on occasion. This is what is meant in Chagigah 13 that as of the time when the Temple was destroyed the wingspan of the chayot which were to cover the feet of the chayah described as possessing the feet of a calf in Ezekiel 1,9 was diminished so that the lower part of these feet remained exposed. Unless the wingspan of this chayah had been diminished, how would Ezekiel have known that its feet were like the feet of a calf? It is possible that in his vision of this chayah it had briefly raised its wings so that its feet and their shape became visible. If we were not to accept this possibility, how would Ezekiel have been able to identify the faces of the chayot in his vision? Surely the explanation must be that the wings moved momentarily to reveal what was hidden behind them. The Midrash rejects this kind of reasoning out of hand. It considers it as normal that the wings momentarily exposed the faces, as faces are to be revealed by definition. If a face were not to be visible and therefore identifiable, it would simply not qualify for the definition “face.” Feet, however, are not subject to being exposed. Hence the fact that the feet of this particular chayah looked like that of a calf is proof of something unusual, i.e. that the wingspan of the chayah was shortened so that it was unable to cover the feet with its wings. The purpose of all this was to remind the prophet and through him the Jewish people of the sin of the golden calf and that though G’d no longer had an account to settle with us, He had not “forgotten” about it having occurred. Such a mention, remembrance, of that sin, while not producing retribution, does make the application of the attribute of Mercy more difficult, “weakens” that attribute when we invoke it. I will discuss this subject when discussing the law of ציצית, the wearing of which is meant to remind us of G’d’s commandments (Numbers 16,38).
