Daniel 1:7

And Scripture says, "And the king told Ashpenaz the chief of the eunuchs to bring in some of those from the sons of the captivity of Israel and from the seed of the king and from the princes, young men, who have no blemish, who are beautiful in appearance and are understanding in all wisdom, being well versed in knowledge, disposed to prudence, and who have in themselves the strength to stand in the house of the king, and to teach them the letters and the tongue of the Chaldeans. And the king appointed them on that very day to be nourished from the table of the king and from the wine which he drank in order for them to be nourished three years, and after these things to stand before the king. And there was among them from the sons of Judah, Daniel and Hanniah, Mishael, and Azariah." [Daniel 1:3-7] It is necessary that those who love learning to not read these things cursorily, but to prepare the mind for the things that lie before us. For the divine writings do not idly preach to us, but their admonition is meant for us and also the blessing of these prophets and the demonstration of all the things which are spoken by them are for us as well. For when Hezekiah king of Judah was sick unto death, then "Isaiah the prophet came to him and told him 'Set in order your sons and your daughters and your father's house, for you will die and you will not live.'" [2 Kings 20:1, also see Isaiah 38:1] Having been grieved at this word, "Hezekiah turned his face to the wall and prayed to the Lord saying, 'Lord remember me just as I have walked before you in truth and in faith and with a full heart and I have done what is pleasing in your presence.' And Hezekiah wept with great weeping." [2 Kings 20:1-3] After this occurred, Isaiah was sent to him a second time and he said to him, "The Lord the God of David your father says this, 'I have heard your prayer and have seen your tears.

Gave names - That is, other names, relating to the idol-gods. Belteshazzar - So Daniel had the name of Belteshazzar, from the great Babylonian idol Baal or Bell. This was by the king's command, and herein he put forth an act: of his sovereignty.

Unto whom the prince of the eunuchs gave names,....

To the last the three youths were consigned when refusing to worship the golden image (Da 3:12). The Chaldee version translates "Lucifer," in Isa 14:12, Nogea, the same as Nego. The names thus at the outset are significant of the seeming triumph, but sure downfall, of the heathen powers before Jehovah and His people.

Unto whom the prince of the eunuchs gave names - This change of names, Calmet properly remarks, was a mark of dominion and authority. It was customary for masters to impose new names upon their slaves; and rulers often, on their ascending the throne, assumed a name different from that which they had before. דניאל Daniel signifies “God is my Judge.” This name they changed into בלטשאצר Belteshatstsar; in Chaldee, “The treasure of Bel,” or “The despository of the secrets (or treasure) of Bel.” הנניה Hananiah signifies, “The Lord has been gracious to me,” or “He to whom the Lord is gracious.” This name was changed into שדרך Shadrach, Chaldee, which has been variously translated: “The inspiration of the sun;” “God the author of evil, be propitious to us;” “Let God preserve us from evil.” מישאל Mishael signifies “He who comes from God.” Him they called מישך Meshach, which in Chaldee signifies, “He who belongs to the goddess Sheshach,” a celebrated deity of the Babylonians, mentioned by Jeremiah, Jer 25:26. עזריה Azariah, which signifies “The Lord is my Helper,” they changed into אבד נגו Abed-Nego, which in Chaldee is “the servant of Nego,” who was one of their divinities; by which they meant either the sun, or the morning star; whether Jupiter or Venus. The vicious pronunciation of this name should be carefully avoided; I mean that which lays the accent on the first syllable, and hurries so the end, without attending to the natural division of the word Abed-Nego.
