Unto whom the prince of the eunuchs gave names - This practice is common in Oriental courts. “The captive youths referred to in the notes on Daniel 1:5, in the Turkish court also receive new names, that is, Mahometan names, their former names being Christian.” - “Pict. Bible.” It is “possible” that this changing of their names may have been designed to make them forget their country, and their religion, and to lead them more entirely to identify themselves with the people in whose service they were now to be employed, though nothing of this is intimated in the history. Such a change, it is easy to conceive, might do much to make them feel that they were identified with the people among whom they were adopted, and to make them forget the customs and opinions of their own country. It is a circumstance which may give some additional probability to this supposition, that it is quite a common thing now at missionary stations to give new names to the children who are taken into the boarding-schools, and especially the names of the Christian benefactors at whose expense they are supported. Compare the same general character, for this change of names may have been, that the name of the true God constituted a part of their own names, and that thus they were constantly reminded of him and his worship. In the new names given them, the appellation of some of the idols worshipped in Babylon was incorporated, and this might serve as remembrancers of the divinities to whose service it was doubtless the intention to win them.
For he gave unto Daniel the name of Belteshazzar - The name Belteshazzar (בלטשׁאצר bêlṭesha'tstsar) is compounded of two words, and means according to Gesenius, “Bel’s prince;” that is, he whom Bel favors. “Bel” was the principal divinity worshipped at Babylon (notes, Isaiah 46:1), and this name would, therefore, be likely to impress the youthful Daniel with the idea that he was a favorite of this divinity, and to attract him to his service. It was a flattering distinction that he was one of the favorites of the principal god worshipped in Babylon, and this was not improbably designed to turn his attention from the God whose name had been incorporated in his own. The giving of this name seemed to imply, in the apprehension of Nebuchadnezzar, that the spirit of the gods was in him on whom it was conferred. See Daniel 4:8-9.
And to Hananiah, of Shadrach - The name “Hananiah” (חנניה chănanyâh) means, “whom Jehovah has graciously given,” and is the same with Ananias (Greek, Ανανίας Ananias), and would serve to remind its possessor of the name of “Jehovah,” and of his mercy. The name Shadrach (שׁדרך shadrak), according to Lorsbach, means “young friend of the king;” according to Bohlen, it means “rejoicing in the way,” and this last signification is the one which Gesenius prefers. In either signification it would contribute to a forgetfulness of the interesting significancy of the former name, and tend to obliterate the remembrance of the early training in the service of Jehovah.
And to Mishael, of Meshach - The name “Mishael” (מישׁאל mı̂yshâ'êl) means, “who is what God is?” - from מי mı̂y “who,” שׁ sha “what,” and אל ēl “God.” It would thus be a remembrancer of the greatness of God; of his supremacy over all his creatures, and of his “incomparable” exaltation over the universe. The signification of the name “Meshach” (מישׁך mêyshak) is less known. The Persian word ovicula means a little sheep (Gesenius), but why this name was given we are not informed. Might it have been on account of his beauty, his gentleness, his lamb-like disposition? If so, nothing perhaps would be better fitted to turn away the thoughts from the great God and his service to himself.
And to Azariah, of Abednego - The name “Azaziah” (עזריה ‛ăzaryâh) means, “whom Jehovah helps,” from עזר ‛âzar “to help,” and יה yâh, the same as “Jah” (a shortened form of Jehovah, יהוה yehovâh), This name, therefore, had a striking significancy, and would be a constant remembrancer of the true God, and of the value of his favor and protection. The name Abed-nego (עבד נגו ‛ăbêd negô) means, “a servant of Nego,” or perhaps of “Nebo” - נבו nebô. This word “Nebo,” among the Chaldeans, probably denoted the planet Mercury. This planet was worshipped by them, and by the Arabs, as the celestial scribe or writer. See the notes at Isaiah 46:1. The Divine worship paid to this planet by the Chaldeans is attested, says Gesenius, by the many compound proper names of which this name forms a part; as Nebuchadnezzar, Nebushasban, and others mentioned in classic writers; as Nabonedus, Nabonassar, Nabonabus, etc. This change of name, therefore, was designed to denote a consecration to the service of this idol-god, and the change was eminently adapted to make him to whom it was given forget the true God, to whom, in earlier days, he had been devoted. It was only extraordinary grace which could have kept these youths in the paths of their early training, and in the faithful service of that God to whom they had been early consecrated, amidst the temptations by which they were now surrounded in a foreign land, and the influences which were employed to alienate them from the God of their fathers.
