Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, with the statutes and judgments.
Remember ye the law of Moses. "The law and all the prophets" were to be in force until John (Matthew 11:13), no prophet intervening after Malachi; therefore they are told, "Remember the law;" for in the absence of living prophets they were likely to forget it. The office of Christ's forerunner was to bring them back to the law, which they had too much forgotten, and so "to make ready a people prepared for the Lord" at His coming (Luke 1:17). God withheld prophets for a time, that men might seek after CHRIST with the greater desire (Calvin). The history of human advancement is marked by periods of rest, and again progress. So in revelation: it is given for a time; then during its suspension men live on the memories of the past. After Malachi there was a silence of 400 years; then a harbinger of light in the wilderness, ushering in the brightest of all the lights that had been manifested, but short-lived; then eighteen centuries during which we have been guided by the light that shone in that last manifestation. The silence has been longer than before, and will be succeeded by a more glorious and awful revelation than ever! John the Baptist was to "restore" the defaced image of "the law," so that the original might be recognized when it appeared among men (Hinds). Just as "Moses" and "Elias" (Malachi 4:5) are here connected with the Lord's coming, so at the transfiguration they converse with Him, implying that the law and prophets which had prepared His way were now fulfilled in Him.
With the statutes and judgments - ceremonial "statutes;" "judgments" in civil questions at issue. "The law" refers to morals and religion.
