John Trapp on Jeremiah 18:13

Ver. 13. Therefore thus ſaith the Lord] God himſelf ſeemeth here to wonder at the deſperate obſtinacy of this people, as not to be matched again. Like as our Saviour marvelled at the unbelief of the Nazarites, and could do for them no mighty work, Mar. 6.5, 6. See the Notes there.

The Virgin of Iſrael hath done a very horrible thing] A Virgin ſhe is called, either by an Irony, or elſe becauſe ſhe ſhould have been a pure Virgin, ſincere in Gods Service, but was nothing leſſe. What this horrible thing was, ſee ver. 15. Confer chap. 2.13, 32.
