John Trapp on Jeremiah 38:6

Ver. 6. Then took they Jeremiah] Whom the King had now (againſt his conſcience, as afterwards Pilate dealt by Jeſus) either through fear, or favour, betrayed unto his deadly enemies: and ſo he was in a pittiful plight, in a forlorn condition. But Jeremiah De profundit, out of the deep called upon God (whom he found far more facile then theſe Princes did Zedekiah) Thou dreweſt near, ſaith he, in the day when I called upon thee, Thou ſaideſt fear not, Lam. 3.57. I called upon thy name O Lord, out of the low dungeon.

And they let down Jeremiah with cords] With a murtherous intent there to make an end of him privily, ut ibi praefocatus moreretur; ille vero uſque ad collum merſus ibi manebat, ſaith Joſephus; that he might there pine and periſh: but God graciouſly prevented it.

And in the dungeon there was no water but mire] A typical hell it was, worſe then Joſephs pit, Gen. 37. or Hemans lake, Pſal. 88.6. or any priſon that ever Brown the Sect maſter ever came into, who uſed to boaſt that he had been committed to two and thirty priſons: and in ſome of them he could not ſee his hand at noon-day. Fullers Church-hiſt. p. 168. He dyed at length in Northampton jayle, Anno 1630. whereto he was ſent for ſtriking the Conſtable requiring rudely the payment of a rate.

So Jeremiah ſunk in the mire] Up to the neck, ſaith Joſephus: and ſo became a type of Chriſt, Pſal. 69.2.
