The King James Bible addresses comfort in several passages:
2 Corinthians 1:3-4 (KJV)
3 Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; 4 Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God.
Psalms 23:4 (KJV)
4 Yea, though I walk through the valley of the shadow of death, I will fear no evil: for thou art with me; thy rod and thy staff they comfort me.
Matthew 5:4 (KJV)
4 Blessed are they that mourn: for they shall be comforted.
Isaiah 40:1 (KJV)
1 Comfort ye, comfort ye my people, saith your God.
John 14:16-17 (KJV)
16 And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever; 17 Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you.
