Charles Spurgeon Commentary Jeremiah 31:15

"Thus saith Jehovah: A voice is heard in Ramah, lamentation, and bitter weeping, Rachel weeping for her children; she refuseth to be comforted for her children, because they are not." — Jeremiah 31:15 (ASV)

Thus saith the LORD; A voice was heard in Ramah, lamentation, and bitter weeping; Rahel weeping for her children refused to be comforted for her children, because they were not.

There is here a prophetic allusion to the massacre of the infants by Herod at the time of the birth of our Lord. It was a time of sorrow indeed.
