Adam Clarke on Daniel 4:36

It is very likely that this unfortunate king had so concealed himself that the place of his retreat was not found out; and the providence of God had so watched over every thing, that, on his return to his palace, he found his counselors and his lords, who received him gladly, and cleaved to and served him as they had formerly done.
