John 3:14-15 King James Version (KJV)
14 And as Moses lifted up the serpent in the wilderness, even so must the Son of man be lifted up:
15 That whosoever believeth in him should not perish, but have eternal life.
John 3:14-15 Amplified Bible, Classic Edition (AMPC)
14 And just as Moses lifted up the serpent in the desert [on a pole], so must [so it is necessary that] the Son of Man be lifted up [on the cross],
15 In order that everyone who believes in Him [who cleaves to Him, trusts Him, and relies on Him] may [a]not perish, but have eternal life and [actually] live forever!
