31 Lit., “if you.” In the Hebrew text vv. 13–14 are one long conditional sentence. The protasis (“if” clauses appear in v. 13), with the apodosis (“then” clause) appearing in v. 14.
32 Heb “if you turn from the Sabbath your feet.”
33 Heb “[from] doing your desires on my holy day.” The Qumran scroll 1QIsaa supplies the preposition מִן (min) on “doing.”
34 Heb “and call the Sabbath a pleasure”; , , , , “a delight.”
35 Heb “and [call] the holy [day] of the Lord honored.” On קָדוֹשׁ (qadosh, “holy”) as indicating a time period, see 872 2.e (cf. also Neh 8:9–11).
36 Heb “and you honor it [by refraining] from accomplishing your ways, from finding your desire and speaking a word.” It is unlikely that the last phrase (“speaking a word”) is a prohibition against talking on the Sabbath; instead it probably refers to making transactions or plans (see Hos 10:4). Some see here a reference to idle talk (cf. 2 Sam 19:30).
37 For a parallel use of the phrase “find joy in” (Hitpael of עָנַג [’anag] followed by the preposition עַל [’al]), see Ps 37:4.
38 Heb “and I will cause you to ride upon the heights of the land.” The statement seems to be an allusion to Deut 32:13, where it is associated, as here, with God’s abundant provision of food.
39 Heb “and I will cause you to eat the inheritance of Jacob your father.” The Hebrew term נַחֲלָה (nakhalah) likely stands by metonymy for the crops that grow on Jacob’s “inheritance” (i.e., the land he inherited as a result of God’s promise).
40 Heb “for the mouth of the Lord has spoken.” The introductory כִּי (ki) may be asseverative (as reflected in the translation) or causal/explanatory, explaining why the preceding promise will become reality (because it is guaranteed by the divine word).

“If you turn back your foot from the Sabbath,

from doing your pleasure 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 your own pleasure, or talking idly;

then you shall take delight in the Lord,

and I will make you ride on the heights of the earth;

I will feed you with the heritage of Jacob your father,

for the mouth of the Lord has spoken.”

and from doing as you please on my holy day,

if you call the Sabbath a delight

and the Lord’s holy day honorable,

and if you honor it by not going your own way

and not doing as you please or speaking idle words,

then you will find your joy in the Lord,

and I will cause you to ride in triumph on the heights of the land

and to feast on the inheritance of your father Jacob.”

For the mouth of the Lord has spoken.

“If you keep from desecrating the Sabbath,

from doing whatever you want on my holy day;

if you call the Sabbath a delight,

and the holy day of the Lord honorable;

if you honor it, not going your own ways,

seeking your own pleasure, or talking business;

then you will delight in the Lord,

and I will make you ride over the heights of the land,

and let you enjoy the heritage of your father Jacob.”

For the mouth of the Lord has spoken.

NLTNew Living Translation

“Keep the Sabbath day holy.

Don’t pursue your own interests on that day,

but enjoy the Sabbath

and speak of it with delight as the Lord’s holy day.

Honor the Sabbath in everything you do on that day,

and don’t follow your own desires or talk idly.

Then the Lord will be your delight.

I will give you great honor

and satisfy you with the inheritance I promised to your ancestor Jacob.

I, the Lord, have spoken!”

LEBThe Lexham English Bible

If you hold your foot back from the Sabbath,

from doing your affairs on my holy day,

if you call the Sabbath a pleasure,

the holy day of Yahweh honorable,

if you honor him more than doing your ways,

than finding your affairs and speaking a word,

then you shall take your pleasure in Yahweh,

and I will make you ride upon the heights of the earth,

and I will feed you the heritage of Jacob your ancestor,

for the mouth of Yahweh has spoken.”

KJV 1900King James Version

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.
