Albert Barnes Commentary Jeremiah 15:1

"Then said Jehovah unto me, Though Moses and Samuel stood before me, yet my mind would not be toward this people: cast them out of my sight, and let them go forth." — Jeremiah 15:1 (ASV)

Cast them out of my sight - Rather, “send them out of My presence, and let them go away.” The prophet is to dismiss them, because their mediators, Moses and Samuel, whose intercession had been accepted in old times (marginal references), would intercede now in vain.
