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?
Isaiah 58:6 fasting neighbor slavery
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.
Isaiah 58:13-14 sabbath
