Jeremia 13:23

Judah will not escape this ignominious lot, since wickedness has so grown to be its nature, that it can as little cease therefrom and do good, as an Ethiopian can wash out the blackness of his skin, or a panther change it spots. The consequential clause introduced by גּם אתּם connects with the possibility suggested in, but denied by, the preceding question: if that could happen, then might even ye do good. The one thing is as impossible as the other. And so the Lord must scatter Judah among the heathen, like stubble swept away by the desert wind, lit., passing by with the desert wind. The desert wind is the strong east wind that blows from the Arabian Desert; see on Jer 4:11.

Still the prophet is attempting to awaken this secure and stubborn people to repentance, by the consideration of the judgments of God that were coming upon them. He is to tell them, I. By the sign of a girdle spoiled that their pride should be stained (Jer 13:1-11). II. By the sign of bottles filled with wine that their counsels should be blasted (Jer 13:12-14). III. In consideration hereof he is to call them to repent and humble themselves (Jer 13:15-21). IV. He is to convince them that it is for their obstinacy and incorrigibleness that the judgments of God are so prolonged and brought to extremity (Jer 13:22-27).

13:23 an Ethiopian: People have no choice about the color of their skin, just as a leopard has no choice about being spotted. In the same way, God’s people were born trapped by evil. They had no ability to change on their own, and they refused to allow the Lord to change them.
