I will sling out the inhabitants of the land - I will project you with violence from your country. I will send you all into captivity. This discourse, from Jeremiah 10:17, is supposed to have been delivered in the eleventh year of Jehoiakim.

(1) “I will distress them” with the rigors of a siege “that they may feel it, i. e., the distress; or,
(2) “that they may find” Me, God, that which alone is worth finding.
