There is none like unto the God of Jeshurun, who rideth upon the heaven in thy help, and in his excellency on the sky. There is none like unto the God of Jeshurun - We have already seen the literal meaning of Jeshurun, Deuteronomy 32:15; but besides its literal meaning, it seems to be used as an expression of particular affection: hence Calmet understands it as a diminutive of the word Israel. We know that τεκνοι, sons, in the mouth of St. John, signifies much less than τεκνια, which, properly translated, would be beloved children, a term which at once shows the helplessness of the offspring, and the tender affection of the parent. So Jeshurun may be understood here: and hence the Septuagint seem to have apprehended the full force of the word by translating it του ηγαπημενου, the beloved one, the object of God's especial delight.
Israel's God, and God's Israel, have no fellows. What were all the gods of the nations, even supposing they were real beings, in comparison of the Almighty? And what nation under heaven could be compared to the Israel of God? It was, however, from God's excellence that they derived theirs.
Rideth upon the heaven, etc. - Unites heaven and earth in thy defense and support, and comes with irresistible velocity to succor and defend thee, and to discomfit thine adversaries.
