Verses with the word comforter in the Old Testament (3 verses):

Ecclesiastes 4:1
So I returned, and considered all the oppressions that are done under the sun: and behold the tears of such as were oppressed, and they had no comforter; and on the side of their oppressors there was power; but they had no comforter.

Lamentations 1:9
Her filthiness is in her skirts; she remembereth not her last end; therefore she came down wonderfully: she had no comforter. O LORD, behold my affliction: for the enemy hath magnified himself.

Lamentations 1:16
For these things I weep; mine eye, mine eye runneth down with water, because the comforter that should relieve my soul is far from me: my children are desolate, because the enemy prevailed.
