II. How Jeremiah came to the knowledge of this (v. 29): Zephaniah read this letter in the ears of Jeremiah. He did not design to do as Shemaiah would have him, but, as it should seem, had a respect for Jeremiah (for we find him employed in messages to him as a prophet, ch. xxi. 1, xxxvii. 3), and therefore protected him. He that continued in his dignity and power stood more in awe of God and his judgments than he that was now a captive. Nay, he made Jeremiah acquainted with the contents of the letter, that he might see what enemies he had even among the captives. Note, It is kindness to our friends to let them know their foes.
