Matthew Poole and continuators on Jeremiah 7:16

16 Therefore pray not thou for this people, neither lift up cry nor prayer for them, neither make intercession to me: for I will not hear thee.

God forbids his Prophets to pray for them in any kind, by any Cry or Intercession, or running upon me, which shews that God is resolved to root them out, seeing he will admit of no Intercession: according as he charged Moses, Exod. 32.10. and the like chap. 11.14. For God had been wont to suffer himself to be prevailed with by the Mediation of his Servants, as of Moses, Exod. 32.11, 14. Num. 14.19, 20. But now he would admit of no Intercession, see Ezek. 14.14, 20. and chap. 15.1. and the next words. This charge seems to be laid upon the Prophet, partly to take off the envy of the People from him, when they knew he was commanded to do no otherwise, partly to imbolden him in this unpleasing work, laying aside all Compassion. But certainly the Prophet did pray that God would mind his Covenant in saving a remnant, though not that God would revoke his Decree; and to save the body of them.
