Albert Barnes Commentary Jeremiah 1:11

"Moreover the word of Jehovah came unto me, saying, Jeremiah, what seest thou? And I said, I see a rod of an almond-tree." — Jeremiah 1:11 (ASV)

What do you see? - If we admit a supernatural element in prophecy, visions would be the most simple means of communication between God and man.

A rod of an almond tree - Many translate “a staff of almond wood.” The vision would thus signify that God - like a traveler, staff in hand - was just about to set forth upon His journey of vengeance. But the rendering of the King James Version is supported by (Genesis 30:37). The word rendered “almond” comes from a root signifying “to be awake;” and as the almond blossoms in January, it seems to be awake while other trees are still Sleeping, and therefore is a fit emblem of activity.
