(19) The eunuchs.--See Note on Jeremiah 29:2. They were for the most part, if not always, of alien birth (comp. Isaiah 56:3), as in the case of Ebed-melech (Jeremiah 38:7), who had become proselytes on entering the king's service. The prominence given to them indicates that in Judah as in Assyria, and we may add, in all Oriental monarchies, they held high position in the king's court, and had probably, like the princes of Judah and Jerusalem, enriched themselves by lending money to the poorer Israelites, and then bringing them into bondage. It is significant that here they take precedence of the priests, as in Jeremiah 29:2 of the princes.

34:8-22 A Jew should not be held in servitude above seven years. This law they and their fathers had broken. And when there was some hope that the siege was raised, they forced the servants they had released into their services again. Those who think to cheat God by dissembled repentance and partial reformation, put the greatest cheat upon their own souls. This shows that liberty to sin, is really only liberty to have the sorest judgments. It is just with God to disappoint expectations of mercy, when we disappoint the expectations of duty. And when reformation springs only from terror, it is seldom lasting. Solemn vows thus entered into, profane the ordinances of God; and the most forward to bind themselves by appeals to God, are commonly most ready to break them. Let us look to our hearts, that our repentance may be real, and take care that the law of God regulates our conduct.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.
