John Wesley on Jeremiah 31:15

In Ramah - That is, in Canaan, and particularly in Ramah, where Nebuzar - adan, chap.40:1, disposed of the prisoners he had taken, setting some at liberty, ordering others to death, and carrying the rest away to Babylon, which caused a bitter weeping and lamentation. Rachel - Rachel is here brought in, having been buried near that place, as if she were risen up from the grave, and lamented the Jewish nation which came out of her loins (for so Benjamin did, which was one of the two tribes that made the kingdom of Judah.) Were not - Because her children either were not absolutely, being slain by the pestilence, the famine, and the sword of the king of Babylon, or were no longer her children, being transplanted into Babylon. And there was a lamentation like this, when Herod caused the infants of two years old to be slain in Bethlehem, and in the coasts round about Bethlehem, of which Ramah was one.
