Luke 3:6 New English Translation

⁶and all humanity^[a] will see the salvation of God.’”^[b]

Luke 3:6 tn Grk “all flesh.”
Luke 3:6 sn A quotation from Isa 40:3-5. Though all the synoptic gospels use this citation from Isaiah, only Luke cites the material of vv. 5-6. His goal may well be to get to the declaration of v. 6, where all humanity (i.e., all nations) see God’s salvation (see also Luke 24:47).
