In Ashdod are the remains of a Light Tower that was build 1000 years ago to help protect Islam’s first capital, Ramla (not to be confused with Ramallah, currently the de facto administrative capital of the PA).
With regard to light the Bible says:
This is the message we have heard from him and proclaim to you, that God is light, and in him is no darkness at all.
1 John 1:5, ESV
You are the light of the world. A city set on a hill cannot be hidden.
Matthew 5:14, ESV
God’s light is in us, giving us opportunity, ability and authority to be messengers of His goodness in Yeshua, our Messiah!
