Adam Clarke on Jeremiah 31:15

A voice was heard in Ramah - The Ramah mentioned here, (for there were several towns of this name), was situated in the tribe of Benjamin, about six or seven miles from Jerusalem. Near this place Rachel was buried; who is here, in a beautiful figure of poetry, represented as coming out of her grave, and lamenting bitterly for the loss of her children, none of whom presented themselves to her view, all being slain or gone into exile. St. Matthew, who is ever fond of accommodation, applies these words, Mat 2:17, Mat 2:18, to the massacre of the children at Bethlehem. That is, they were suitable to that occasion, and therefore he so applied them; but they are not a prediction of that event.
