Haggai, Zechariah and Malachi, as suggested by C.H. Spurgeon, is 'A capital book', providing exegesis of the text. In addition, at the end of each section, Moore lists a series of practical inferences. These, rather than 'spoon-feed' the reader, indicate how Scripture should be developed in practical application.
'My object', writes Moore, 'has been to furnish such an exposition of the meaning of the text as would be intelligible to any thinking layman who wished to understand the Scriptures thoroughly, and also to aid my brethren in the ministry.'
