Who knoweth if he will return and repent, and leave a blessing behind him; even a meat offering and a drink offering unto the LORD your God?
Who knoweth if he will return and repent, and leave a blessing behind him, even a meat offering and a drink offering - i:e., Who knows but He will still give plentiful harvests, out of the first-fruits of which we may offer the meat and drink offering, now "cut off" through the famine? (Joel 1:9; Joel 1:13; Joel 1:16.) So the king of Nineveh reasoned, "Who can tell if God will turn and repent, and turn away from His fierce anger, that we perish not?" (Jonah 3:9.)
Leave ... behind him - as God, in visiting His people now, has left behind Him a curse, so He will, on returning to visit them, leave behind Him a blessing.
