The princes of Judah, and the princes of Jerusalem
Here is a particular enumeration of the persons that had made the covenant, and transgressed it, and that should suffer for so doing; the princes of Judah, distinguished from the princes of Jerusalem, design such princes as lived without Jerusalem, in the cities of Judah, and presided over them, though now at Jerusalem, having fled thither, upon the invasion of the king of Babylon, for their safety; as the princes of Jerusalem, or the magistrates of that city, are distinguished from the princes of the blood, and from the courtiers, both in this and ( Jeremiah 34:21 ) ; the eunuchs, and the priests, and all the people of the land;
that is, as many as had got into Jerusalem to secure themselves from the common enemy: the "priests" also were concerned herein, who had menservants, and maidservants, as well as others; and, besides, were persons doubtless concerned in drawing up the covenant and the form of an oath, as well as in slaying the sacrifice, and cutting it into pieces, and laying the parts in order: it is more surprising that there should be "eunuchs" here; that such should be in the court of the king of Judah, and have offices in it, and preside in them, as among the Gentiles. The Targum renders the word "princes": which passed between the parts of the calf;
signifying their assent to the covenant, and wishing they might be so used if they broke it.
