He destroyed their vines with hail - Margin, killed. See Exodus 9:22-26. In the account in Exodus the hail is said to have smitten man and beast, the herb, and the tree of the field. In the psalm only one thing is mentioned, perhaps denoting the ruin by what would be particularly felt in Palestine, where the culture of the grape was so common and so important.

And their sycamore trees with frost - The sycamore is mentioned particularly as giving poetic beauty to the passage. Of the sycamore tree, Dr. Thomson remarks ("land and the Book," vol. i. p. 25), "It is a tender tree, flourishes immensely in sandy plains and warm vales, but cannot bear the hard, cold mountain. A sharp frost will kill them; and this agrees with the fact that they were killed by it in Egypt. Among the wonders performed in the field of Zoan, David says, 'He destroyed their vines with hail, and their sycamores with frost.' Certainly, a frost keen enough to kill the sycamore would be one of the greatest 'wonders' that could happen at the present day in this same field of Zoan." The word rendered "frost" - חנמל chănâmâl - occurs nowhere else. It is parallel with the word hail in the other member of the sentence, and denotes something that would be destructive to trees. The Septuagint, the Vulgate, and the Arabic render it frost. Gesenius renders it ants.

"The Sun of Righteousness"
WE SHOULD FEEL QUITE JUSTIFIED in applying the language of the 19th Psalm to our Lord Jesus Christ from the simple fact that he is so frequently compared to the sun; and especially in the passage which we have given you as our second text, wherein he is called "the Sun of Righteousness." But we have a higher justification for such a reading of the passage, for it will be in your memories that, in the 10th chapter of the Epistle to the Romans, the Apostle Paul, slightly altering the words of this …

A Jealous God
I. Reverently, let us remember that THE LORD IS EXCEEDINGLY JEALOUS OF HIS DEITY. Our text is coupled with the command--"Thou shalt worship no other God." When the law was thundered from Sinai, the second commandment received force from the divine jealousy--"Thou shalt not make unto thee any graven image, or any likeness of anything that is in the heaven above, or that is in the earth beneath, or that is in the water under the earth; Thou shalt not bow down thyself to them, nor serve them: for I …
