How can Matthew 2:18 be fulfilled prophecy if Ramah is north of Jerusalem and Bethlehem is south?

Regarding the passage Mt 2:13-18. Joseph flees to Egypt with Jesus and Mary after being warned by an angel that Jesus’ life is in danger. Herod then kills all the male children less than 2 years old in and around Bethlehem (8 miles *south* of Jerusalem). Matthew calls this tragic event the fulfillment of Je 31:15: > A cry is heard in Ramah… Rachel weeps for her children… for her children are gone. However, OT verses and sources from bibleatlas.org point to Ramah being 8+ miles *north* of Jerusalem. How can the verses in Matthew and Jeremiah refer to the same place if they are 16+ miles apart? What am I missing?
