What is the signficance of Syria in Matt 4:24?

It reads: "So the news about Him spread throughout all Syria; and they brought to Him all who were sick, those suffering with various diseases and pains, those under the power of demons, and epileptics, paralytics; and He healed them."

Syria was not part of Israel and Yeshua made it a point to say that He only came for the lost sheep of Israel, so why is this stated in Matt 4?
