# A voice was heard ... they were no more

Matthew is quoting the prophet Jeremiah.

# A voice was heard

"People heard a voice" or "There was a loud sound" 

# Rachel weeping for her children

Rachel lived many years before this time. This prophecy shows Rachel, who has died, weeping for her descendants.

# she refused to be comforted

"no one could comfort her" or "she did not let anyone comfort her"

# because they were no more

"because the children were gone forever." This is a mild way of saying they were dead. Alternate translation: "because they were dead"
