Matthew Poole and continuators on Jeremiah 37:3

3 And Zedekiah the king sent Jehucal, the son of Shelemiah, and Zephaniah the son of Maaseiah the priest, to the prophet Jeremiah, saying, Pray now unto the LORD our God for us .

This was apparently in the time of the siege for v. 5. we read of Pharaoh's Army being come to relieve the besieged, whether it was before the Babylonians were departed, or no, is uncertain, but it is plain if they were departed, the King was afraid they would come back again. That which is most observable for us from hence is this, That wicked men of all ranks are desirous of the Prayers of those Ministers in their distresses, whose Councels and Admonitions they never regard, while they are in a time of prosperity, which is an evidence of their acting contrary to the convictions of their Consciences, in obedience to their lusts, in their contempt of their instructions and admonitions. When Affliction hath cooled their Lusts, then their consciences can be heard in dictating their duty to them.
