Psalms 60:4
But for those who fear you, you have raised a banner to be unfurled against the bow.

Numbers 21:8,9
The LORD said to Moses, 'Make a snake and put it up on a pole; anyone who is bitten can look at it and live.' So Moses made a bronze snake and put it up on a pole. Then when anyone was bitten by a snake and looked at the bronze snake, he lived.

Isaiah 11:10-12
In that day the Root of Jesse will stand as a banner for the peoples; the nations will rally to Him, and His place of rest will be glorious. In that day the Lord will reach out His hand a second time to reclaim the remnant that is left of His people from Assyria, from Lower Egypt, from Upper Egypt, from Cush, from Elam, from Babylonia, from Hamath and from the islands of the sea. He will raise a banner for the nations and gather the exiles of Israel; He will assemble the scattered people of Judah from the four quarters of the earth.
