Malachi 4:4

I humbly conceive, that this verse of reminding the people of the law of Moses, was to bring them under the condemning sentence of Moses' law. As the law was the ministration of death, for so the Apostle, commissioned by the Holy Ghost, was directed to call it, 2 Corinthians 3:7. this remembrance of it became very proper, and well timed, when Christ was approaching; intimating, that as the knowledge of sin came by the law, this might be made the schoolmaster unto Christ. Romans 7:7; Galatians 3:24.
