From Barnabas (less then 50%)

Barnabas 3:1
He speaketh again therefore to them concerning these things;
Wherefore fast ye for Me, saith the Lord, so that your voice is
heard this day crying aloud? This is not the fast which have chosen,
saith the Lord; not a man abasing his soul;

Barnabas 3:2
not though ye should bend your neck as a hoop, and put on sackcloth
and make your bed of ashes, not even so shall ye call a fast that is
acceptable.

Barnabas 3:3
But unto us He saith; Behold, this is the fast which I have chosen,
saith the Lord; loosen every band of wickedness, untie the
tightened cords of forcible contracts, send away the broken ones
released and tear in pieces every unjust bond. Break thy bread to
the hungry, and if thou seest one naked clothe him; bring the
shelterless into thy house, and if thou seest a humble man, thou
shalt not despise him, neither shall any one of thy household and
of thine own seed.

Barnabas 3:4
Then shall thy light break forth in the morning, and thy healing
shall arise quickly, and righteousness shall go forth before thy
face, and the glory of God shall environ thee.

Barnabas 3:5
Then shalt thou cry out and God shall hear thee; while thou art
still speaking, He shall say 'Lo, I am here'; if thou shalt take
away from thee the yoke and the stretching forth of the finger and
the word of murmuring, and shalt give thy bread to the hungry
heartily, and shalt pity the abased soul.

Barnabas 3:6
To this end therefore, my brethren, He that is long-suffering,
foreseeing that the people whom He had prepared in His well-beloved
would believe in simplicity, manifested to us beforehand concerning
all things, that we might not as novices shipwreck ourselves upon
their law.
