Charles Ellicott Commentary Daniel 4:26

"And whereas they commanded to leave the stump of the roots of the tree; thy kingdom shall be sure unto thee, after that thou shalt have known that the heavens do rule." — Daniel 4:26 (ASV)

They commanded — i.e., the watchers. We observe, however, in Daniel 4:13 that the command is only ascribed to one of the watchers. This makes it appear that they form a council in which one acts on behalf of all.

Your kingdom. — To make the sense plain, we must supply before this word, “The interpretation of it is,” or some sentence to that effect.

Shall be sure. — Literally, shall arise. No successor shall be appointed during his life.

Do rule — i.e., the heavens, or One in heaven rules the kingdoms of men.
