Lovers of Hebrew will find a kindred spirit in Professor Mackay. Those without Hebrew will find a patient teacher leaving no stone unturned to make the word of God plain.
Alec Motyer, (1924–2016) Well known Bible expositor and commentary writer
"The commentary is as full as is reasonably possible, verse by verse, often word by word, and covers every question likely to be raised."
John L. Mackay's commentary on Jeremiah is a first class explanation of the prophet... It is certain to become the first 'port of call' in my studies of the book,... he has the ability to uncover the significance of the original message in such a way as to leave the application (almost) transparent.
Stephen Dray, Minister, Ferndale Baptist Church, Southend-on-Sea, England
This commentary is refreshing-it actually explains the text of Jeremiah. John L. Mackay knows the critical speculations about the text but doesn't bore us with them. He avoids nothing; he ploughs through every bit of the text and gives a lucid explanation of it. Mackay will not write your sermon for you but gives you what you need to write your sermon - a clear understanding of what the text says.
