John Trapp on Jeremiah 40:16

Ver. 16. Thou ſhalt not do this thing] This juſt man would not have any man dye ixdicta cauſa, before his cauſe had been heard, were he never ſo wicked.

For thou ſpeakeſt falſely of Iſhmael] So Gedaliah thought: but it proved otherwiſe. Iſhmael is pleaded for, but without cauſe. Queen Elizabeth complained that in truſt ſhe had oft found treaſon; So ſhall all Princes: who therefore had need to be very cautelous, and yet not over-credulous. Kingcraft is not eaſily learned.
