Still the fears of Nebuchadnezzar were not allayed. His determination to attack the Holy City ripened only after God Himself had shown him how He had bound the hands of the archangel Michael, the patron of the Jews, behind his back, in order to render him powerless to bring to his wards. So the campaign against Jerusalem was undertaken.
If the Babylonians thought that the conquest of Jerusalem was an easy task, they were greatly mistaken. For three years God endured the inhabitants with strength to withstand the onslaughts of the enemy, in the hope that the Jews would amend their evil ways and abandon their godless conduct, so that the threatened punishment might be annulled.
