13 bIf you turn back your foot from the Sabbath,
from doing your pleasure
Or business
on my holy day,
and call the Sabbath a delight
and the holy day of the Lord honorable;
if you honor it, not going your own ways,
or seeking dyour own pleasure,
Or pursuing your own business
or talking idly;
Hebrew  or speaking a word

14then you shall take delight in the Lord,
gand I will make you ride on the heights of the earth;
Or  of the land

iI will feed you with the heritage of Jacob your father,
jfor the mouth of the Lord has spoken.”
