תּלמוד אויף יחזקאל 1:6

One verse says, "Six wings to the one, six wings to the one (Isaiah 6:2)," and one verse says "And four faces to the one, and four wings to the one (Ezekiel 1:6)." This is not a contradiction. This is during the time when the Temple was standing, and this is when the Temple was not standing (even though it technically was, it was already doomed), and as it were, the wings of the Chayot were lessened.
