Notice the repeated Hebrew word for Banner/Signal (נס) in the following verses:
Exodus 17:15, “And Moses built an altar and called the name of it, ‘YHWH Is My Banner (נס)” – YHWH as נס
Numbers 21:8, “And YHWH said to Moses, ‘Make a fiery serpent and set it on a pole (נס), and everyone who is bitten, when he sees it, shall live.” – Serpent set on נס
Isaiah 11:10-12, “In that day the root of Jesse, who shall stand as a signal (נס)…[the Lord] will raise a signal (נס) for the nations and will assemble the banished of Israel…” – The Messiah as נס raised to gather the nations…
John 3:14-15, “…as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in Him may have eternal life.”
John 3:14-15 unites the imagery of YHWH, the curse, the Messiah, and the beacon raised to gather the nations into one–the crucified Son…
