“Ebed-melech Baruch the son of Neriah. the Cushite Zedekiah. Just as a Cushite is different in his skin, so was Zedekiah different in his righteousness, from all his generation (Moed Katan 16b). And there is a Midrash that expounds “the Cushite,” as referring to Baruch (Sifrei ibid.). an officer Heb. סריס, a great man.”

“In this part is shown the persecution of the prophet on account of his true preaching: and it is divided into three parts. First he sets down the preaching, he was speaking: for although he was in prison, yet many came to him; in which he threatens death to those who remain: whoever shall remain in this city shall die. And he promised safety to those who fled: but whoever shall flee (...) shall live. The capture of the city: by being delivered, it shall be delivered. And these three things he set down above in 21: whence it seems to be continued, according to the order of the history, to that. Secondly he sets down the persecution: where he sets down the impious petition of the princes: for they seek death: and the princes said. Wis. 2: let us circumvent the just man, because he is contrary to our works. They accuse his preaching: for of set purpose he weakens the hands of the men: which is against the prophetic office. Isa. 35: strengthen the weakened hands, and make firm the feeble knees. And they pervert his intention: since this man does not seek peace. Gal. 4: am I then become an enemy, speaking the truth to you? But Jeremiah did not wish to take away the heart of resisting; but he said those things for the good and salvation of the people, at the command of the Lord. He also sets down the foolish assent of the king: and king Zedekiah said. Whence he is not excused, although he sinned less. John 19: therefore he who delivered me to you has the greater sin. He also sets down their diligent execution: they took Jeremiah, therefore, and cast him into the pit, a cistern without water. Ps. 87: they have put me in the lower pit, in the dark places, and in the shadow of death. And he designates the letting down of the prophet: and so Jeremiah went down into the mire. Ps. 68: I am fixed in the mire of the deep, and there is no substance. Thirdly, the liberation is set down. Here he sets down two things. First, that he is freed from prison; secondly, that he is freed from fear of death, there, and king Zedekiah sent, and took Jeremiah to himself. Concerning the first, four things. First he describes the one petitioning, Abdemelech, that is, signifying "servant of the king"; which he says on account of humility. Rom. 1: Paul, a servant of Christ Jesus, etc. An Ethiopian, on account of the mortification of the flesh. Ps. 67: Ethiopia shall hasten her hands unto God. Cant. 1: I am black, but beautiful. A man, on account of strength of soul; a eunuch, on account of chastity. Matt. 19: there are eunuchs who have castrated themselves for the kingdom of heaven. Who was in the house of the king, Phil. 3: our conversation is in the heavens. Wis. 3: the eunuch who has not wrought iniquity with his hands, nor thought most wicked things against God: for to him shall be given the choice gift of faith, and a most acceptable lot in the temple of God. Secondly he sets down the petition, designating the place of the petition: now the king was sitting in the gate of Benjamin, which namely led into the tribe of Benjamin. And he sets down the petition, and Abdemelech went out from the house of the king, and spoke to the king (...) for there is no more bread in the city; as if to say: from the time he was shut in, the bread failed. Or, it was not necessary for him to be shut in, since we are all besieged, and in want. Wis. 11: by what things a man sins, by the same also he is tormented. Thirdly, the obtaining is set down: and so the king commanded. Fourthly, the execution is set down: Abdemelech, therefore, taking men with him, entered the house of the king (...) and took from there old rags and worn-out things that had rotted, on account of the tribulations which they endured. Heb., last chapter: remember the leaders who have spoken to you the word of God; considering the end of their conversation, imitate their faith. Or because, literally, they are softer. By the cords, the precepts of God. Eccl. 4: a threefold cord is broken with difficulty. In the vestibule of the prison, that is, in the court. For the vestibule is called the house before the king's chamber, where garments are kept: whence every court is called a vestibule.”

“Now when Ebedmelech the Ethiopian,.... The Targum renders it, "a servant of King Zedekiah;'' which Jarchi, and other writers, following, make Zedekiah to be the Ethiopian; so called, because as an Ethiopian differs in his skin, so Zedekiah differed in his righteousness, from the rest of his generation; and this his servant, he, with others (r), takes to be Baruch the son of Neriah, but without any foundation; but, as Kimchi observes, with whom Abarbinel and Ben Melech agree, had this word "Ebedmelech" been an appellation, the usual article would have been prefixed before the word "king", as in the next clause; and somewhere or other his name would have been given; but it is a proper name, as Ahimelech, and Abimelech. A servant of the king he might be, and doubtless he was; and perhaps had this name given him when he became a proselyte; for such he seems to be, and a good man; who had a great regard to the prophet, because he was one; and had more piety and humanity in him, though an Ethiopian, than those who were Israelites by birth: one of the eunuchs which was in the king's house; an officer at court; one of the gentlemen of the bedchamber. Josephus (s) says he was in great honour; so the Targum renders it, "a great man;'' a man in high office, of great authority; taking it to be a name of office, as it sometimes is; though it may be understood, in a proper sense, of a castrated person; for such there were very commonly in kings' palaces, employed in one office or another, and especially in the bedchamber: now this man heard that they had put Jeremiah in the dungeon; for though the princes did it with all possible secrecy, it was known at court, and came to the ears of this good man; and indeed the dungeon was not far from the court; and some have thought he might have heard the groans of Jeremiah in it; however, he came to the hearing of it, and was affected with the relation of his case, and determined to save him, if possible: the king then sitting in the gate of Benjamin; the same in which the prophet was taken, Jer 37:13; here he sat to hear and try causes, courts of judicature being held in gates of cities; or to receive petitions; or rather it may be to consult about the present state of affairs, what was best to be done in defence of the city, and to annoy the besiegers; and it may be to have a view of the enemy's camp, and to sally out upon them; for that he was here in order to make his escape is not likely.

“Ebed-melech--The Hebrew designation given this Ethiopian, meaning "king's servant." Already, even at this early time, God wished to show what good reason there was for calling the Gentiles to salvation. An Ethiopian stranger saves the prophet whom his own countrymen, the Jews, tried to destroy. So the Gentiles believed in Christ whom the Jews crucified, and Ethiopians were among the earliest converts (Act 2:10, Act 2:41; Act 8:27-39). Ebed-melech probably was keeper of the royal harem, and so had private access to the king. The eunuchs over harems in the present day are mostly from Nubia or Abyssinia.”
