3:5 Every valley will be filled, 1
and every mountain and hill will be brought low,
and the crooked will be made straight,
and the rough ways will be made smooth,
3:6 and all humanity 2 will see the salvation of God.’” 3
1 sn The figurative language of this verse speaks of the whole creation preparing for the arrival of a major figure, so all obstacles to his approach are removed.
2 tn Grk “all flesh.”
3 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).
