And mark the promise that is to such Sabbath-keepers, in the fourteenth verse, _Then shalt thou delight thyself in the Lord, and I will cause thee to ride upon the high places of the earth, and will feed thee with the heritage of Jacob thy father; for the mouth of the Lord hath spoken it._ First, they shall delight themselves in the Lord, and that will make the Sabbath a delight. Second, they shall ride upon the high places of the earth; the high places of the earth holding forth, as I conceive, the great opposition, whether of great and mighty men, or great walled cities, according to that in Deut. 1:28, which hath an allusion to Israel's subduing the land of Canaan. Deut. 32:13. Thou shalt ride upon them, that is, subdue and conquer them. Psalm 45:4, 66:12. _They shall tread upon their high places._ Deut. 33:39. _They shall be as ashes under the soles of their feet._ Mal. 4:3. Now, when did the Lord's people do such work as this since this prophesy? or, is it yet to be fulfilled? Again, consider what the Lord saith in Isa. 56:6, 7, _Also the sons of the stranger that join themselves to the Lord, to serve him, and to love the name of the Lord, to be his servants, every one that keepeth the Sabbath from polluting it, and taketh hold of my covenant, even them will I bring to my holy mountain, and make them joyful in my house of prayer; their burnt offerings and their sacrifices shall be accepted upon mine altar, for mine house shall be called an house of prayer to all people._ By the sons of the stranger, I understand is here meant Gentiles, who were strangers to the commonwealth of Israel and afar off, but are now made nigh by the blood of Christ, and so they join themselves to the Lord, and serve him, and love the name of the Lord; these are such as keep the Sabbath, and take hold of God's covenant, and it is such a Sabbath as may be polluted, and therefore not Christ's, as some would have it. Now, the promises that are made to these strangers, do look at clear gospel times. They shall be brought into God's holy mountain, and there be made joyful, when it is so mountainous that it is the house of prayer for all people, or for all nations, as Christ saith in Matt. 11:17. _Blessed is the man that doeth this, and the son of man that taketh hold on it, that keepeth the Sabbath from polluting it, and keepeth his hand from doing any evil. Thus saith the Lord unto the eunuchs that keep my Sabbath, and choose the things that please me, and take hold on my covenant, even unto them will I give a name and a place better than of sons and daughters; I will give them an everlasting name, that shall not be cut off._ Isa. 56:2, 4, 5. The eunuchs are such as care for the things that please the Lord, when the married careth for the things that please his wife. Cor. 7:32, 33. And when two parts shall be cut off and die, the eunuchs that keep the Sabbath shall have an everlasting name, which shall not be cut off.
