1 Kings 16:24

He bought the hill Samaria of Shemer Where he built the noted city of that name, which ever after was the royal city of the kings of Israel, the palace of Tirzah being burned. This city, in process of time, became so considerable, that it gave name to the middle part of Canaan, which lay between Galilee on the north, and Judea on the south, and to the inhabitants of that country, who were called Samaritans. For two talents of silver Something more than seven hundred pounds sterling. “Perhaps,” says Henry, “Shemer let him have the ground cheaper, on condition that it should be called after his name: for it was called Samaria, or Shemeren, as it is in the Hebrew, from Shemer, the former owner of the land.” Thus the kings of Israel often changed the seat of their government, which was Shechem first then Tirzah, now Samaria. But the kings of Judah were constant to Jerusalem, the city of God.
