The wrath of God came upon them - See Numbers 11:33.

And slew the fattest of them - literally, "slew among their fat ones." That is, The most vigorous among them were cut down; the people most eminent for rank, for influence, for strength, for valor. How far this was the natural effect of indulgence in eating, and how far it was a direct miracle, cannot now be ascertained. In either case it would equally show the divine displeasure.

And smote down - Margin, as in Hebrew, "made to bow." That is, they were made to bow in death.

The chosen men of Israel - Margin, "Young men." The idea is that of select men; men that would be chosen from among the others; men distinguished for vigor or influence. Not the aged or the feeble particularly, not those who might be naturally expected to fall, but men of strength who might be supposed to be capable of resisting the ordinary attacks of disease. God showed in this way that the judgment came directly from his hand.

"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 …
