Then shalt thou delight thyself in the Lord,.... In his perfections; in his omnipotence, omniscience, omnipresence, eternity, immutability, holiness, justice, truth, and faithfulness; in his wisdom, love, grace, and mercy, especially as displayed in Christ, and salvation by him; in the relations he stands in to his people, as their covenant God and Father, and in what he is to them, their shield and exceeding great reward, their portion and inheritance; in his works of creation, providence, and grace; in his word, the Gospel, the truths, doctrines, and promises of it; in his ways and worship: in his ordinances and commandments; in communion with him, and with his people; in all which, abundance of delight, pleasure, and satisfaction, is found by those who know him in Christ, have tasted that he is gracious; who have some likeness to him, love him, and are the objects of his love and delight:and I will cause thee to ride upon the high places of the earth; to live above the world, and to have their conversation in heaven; to be in the utmost safety, and enjoy the greatest plenty, especially of spiritual things: or to be superior to the men of the world, even the highest of them; to have power and authority in the earth, as the saints will have in the latter day; particularly this will be true when the mountain of the Lord's house is established upon the top of the mountains, Isa 2:2:and feed thee with the heritage of Jacob thy father: the Jewish writers inquire why Jacob is mentioned, and not Abraham nor Isaac; and answer, as in the Talmud , not Abraham, of whom it is written, "arise, walk through the land in the length of it", &c.
Ge 13:17, nor Isaac, of whom it is written, "for unto thee, and to thy seed, will I give all these countries", &c. Ge 26:3, but Jacob, of whom it is written, "and thou shalt spread abroad to the west, and to the east, and to the north, and to the south", &c.
Ge 28:14 expressing the larger extent of the inheritance; so Jarchi and Samson account for it; but Kimchi gives a better reason, because the sons of Jacob, and not Ishmael the son of Abraham, nor Esau the son of Isaac, inherited the land of Canaan: but rather the reason is, because he is the father of all true Israelites, who are, as he was, wrestling and prevailing; these the Lord feeds with spiritual provisions here, and glory hereafter; which the good things of the land of Canaan, the inheritance of Jacob and his sons, were a type of: and perhaps this may have respect to the conversion of the Jews, when they shall return to their own land, and enjoy the good things of it, as well as all spiritual blessings:for the mouth of the Lord hath spoken it; who is faithful to his covenant, true to his word; cannot lie, will never deceive; performs whatsoever he has promised, being able to do it; and therefore it may be depended upon that all this shall be as he has said.
T. Bab. Sabbat, fol 118. 2.
