Charles Ellicott Commentary Jeremiah 26:4-5

"And thou shalt say unto them, Thus saith Jehovah: If ye will not hearken to me, to walk in my law, which I have set before you, to hearken to the words of my servants the prophets, whom I send unto you, even rising up early and sending them, but ye have not hearkened;" — Jeremiah 26:4-5 (ASV)

To walk in my law, which I have set before you. —The words present more vividly than in the parallels of Jeremiah 7:25; Jeremiah 25:4 the relation of the Law as the groundwork of the teaching of the Prophets, their office being that of preachers and expounders, making people feel that the commandment was exceeding broad. The Law and the Prophets are already coupled together, as in Matthew 5:17; Matthew 22:40, as making up God’s revelation of His will to Israel.
