Jeremiah 23:33

When this people, or the prophet, &c., shall ask thee, &c. “The remaining part of this chapter is directed against those who called the word of God, spoken by the true prophets, A BURDEN, by way of reproach; meaning that it always portended evil, and never good;” the word משׁא, a burden, generally signifying a calamitous prophecy. See note on Isaiah 13:1. “Ahab intended to cast the same slur on the Prophet Micaiah when he represented him as one that never prophesied good concerning him, but evil, 1 Kings 22:8.” The false prophets, who said, Peace, peace, it seems, derided the true prophets, whose predictions were full of threatenings, as if God's messages were a burden which they were weary of hearing; and made a jest of these words, The burden of the Lord, with which God's prophets sometimes prefaced their prophecies. Upon this account God forbade the use of that expression, as in the following verses. See Lowth.
