Albert Barnes Commentary Ezekiel 17:9

"Say thou, Thus saith the Lord Jehovah: Shall it prosper? shall he not pull up the roots thereof, and cut off the fruit thereof, that it may wither; that all its fresh springing leaves may wither? and not by a strong arm or much people can it be raised from the roots thereof." — Ezekiel 17:9 (ASV)

Her spring - Rather, her growth.

Even without ... - Translation: and not with great power or with many people is it to be raised up from its roots again.
