Matthew Poole and continuators on Jeremiah 18:10

10 If it do evil in my sight, that it obey not my voice, then I will repent of the good wherewith I said that I would benefit them

Speaking verse 9. and repenting verse 10. must be understood in the same sense as in the two former verses. The reason of this is because in all Gods threatnings and promises of this nature there is a condition either expressed or understood, Gods threatnings of evil must be understood with this condition unless men and women repent and turn from their evil wayes: and his promises of good must be understood with this condition, if those to whom they are made be a willing and obedient people, and keep in the way of the Lords Statutes.
