“Shield of David” — the six-pointed star on Israel's flag; the image itself is Scripture's, where God is the shield of His people
also written: magen david, mogen david
In Scripture
World English Bible
After these things Yahweh’s word came to Abram in a vision, saying, “Don’t be afraid, Abram. I am your shield, your exceedingly great reward.”
Genesis 15:1
Scripture calls God Abram’s shield; it does not call the later six-pointed emblem the Shield of David.
God, my rock, in him I will take refuge; my shield, and the horn of my salvation, my high tower, and my refuge. My savior, you save me from violence.
2 Samuel 22:3
David names God his shield, supplying the biblical image behind the later phrase.
