Thematic Bible: The crooked

Comfort, comfort My people, says your God. Speak tenderly to the heart of Jerusalem, and cry to her that her time of service and her warfare are ended, that [her punishment is accepted and] her iniquity is pardoned, that she has received [punishment] from the Lord's hand double for all her sins. A voice of one who cries: Prepare in the wilderness the way of the Lord [clear away the obstacles]; make straight and smooth in the desert a highway for our God! read more.
Every valley shall be lifted and filled up, and every mountain and hill shall be made low; and the crooked and uneven shall be made straight and level, and the rough places a plain.

As it is written in the book of the words of Isaiah the prophet, The voice of one crying in the wilderness [shouting in the desert]: Prepare the way of the Lord, make His beaten paths straight. Every valley and ravine shall be filled up, and every mountain and hill shall be leveled; and the crooked places shall be made straight, and the rough roads shall be made smooth; And all mankind shall see (behold and understand and at last acknowledge) the salvation of God (the deliverance from eternal death decreed by God).
