John Trapp on Isaiah 66:4

Ver. 4. I alſo will chuſe their deluſions] As they have had their will, ſo will I have mine another while. I will make them to periſh by their mockeries, idque ex lege talionis, See chap. 65.11.12. They thought to cozen me by an out-ſide-ſervice: but it ſhall appear that they have cozened themſelves, when I bring upon them mercedem multiplicis petulantiae corum (as Piſcator rendereth it) the reward of their manyfold petulancies, and illuſions.

And will bring their fear upon them] Inducam nivem ſuper eos qui timuerunt à pruina. They have feared the coming of the Chaldees, and come they ſhall. So their poſterity feared the Romans, Joh. 11. and they felt their fury. See Prov. 10.24. with the Note.

Becauſe when I called, &c.] See chap. 65.12.
