This study investigates the function of Malachi 3:22 in the context of prophetic eschatology as reflected in Malachi’s message about the delay of the expected Day of the Lord, which focuses on the charge to ‘remember the law of my servant Moses (…) I gave him at Horeb for all Israel’. This article examines the question how this charge serves the purpose of awaiting in the interim time the advent of the Day of the Lord. Firstly, a textual analysis is given of Malachi 3:22 in the context of the body of the book. Secondly, an eschatological application of the text is attempted with the help of selected texts from Deuteronomy 12:5, 11 (on worship) and 24:1–4 (on the treatment of women), addressing the problems in Malachi 1:6–2:9 and 2:10–16. Thirdly, the missional inferences of Malachi 3:22 for the present time are condensed in a postscript.
