Isaiah 58 - KJV

Is not this the fast that I have chosen?
to loose the bands of wickedness,
to undo the heavy burdens,
and to let the oppressed go free,
and that ye break every yoke?

If thou turn away thy foot from the sabbath,
from doing thy pleasure on my holy day;
and call the sabbath a delight,
the holy of the Lord, honourable;
and shalt honour him, not doing thine own ways,
nor finding thine own pleasure,
nor speaking thine own words:
Then shalt thou delight thyself in the Lord;
and I will cause thee to ride upon the high places of the earth,
and feed thee with the heritage of Jacob thy father:
for the mouth of the Lord hath spoken it.
