Unto whom the prince of the eunuchs {l} gave names: for he gave unto Daniel the name of Belteshazzar; and to Hananiah, of Shadrach; and to Mishael, of Meshach; and to Azariah, of Abednego.

(l) That they might altogether forget their religion: for the Jews gave their children names which might always put them in remembrance of some point of religion. Therefore this was a great temptation and a sign of servitude, which they were not able to resist.

Wesley's Notes

1:7 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.

Jamieson-Fausset-Brown Bible Commentary

7. gave names-designed to mark their new relation, that so they might forget their former religion and country (Ge 41:45). But as in Joseph's case (whom Pharaoh called Zaphnath-paaneah), so in Daniel's, the name indicative of his relation to a heathen court ("Belteshazzar," that is, "Bel's prince"), however flattering to him, is not the one retained by Scripture, but the name marking his relation to God ("Daniel," God my Judge, the theme of his prophecies being God's judgment on the heathen world powers).

Hananiah-that is, "whom Jehovah hath favored."

Shadrach-from Rak, in Babylonian, "the King," that is, "the Sun"; the same root as in Abrech (Ge 41:43, Margin), "Inspired or illumined by the Sun-god."

Mishael-that is, "who is what God is?" Who is comparable to God?

Meshach-The Babylonians retained the first syllable of Mishael, the Hebrew name; but for El, that is, God, substituted Shak, the Babylonian goddess, called Sheshach (Jer 25:26; 51:41), answering to the Earth, or else Venus, the goddess of love and mirth; it was during her feast that Cyrus took Babylon.

Azariah-that is, "whom Jehovah helps."

Abed-nego-that is, "servant of the shining fire." Thus, instead of to Jehovah, these His servants were dedicated by the heathen to their four leading gods [Herodotus, Clio]; Bel, the Chief-god, the Sun-god, Earth-god, and Fire-god. 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.

Matthew Henry's Concise Commentary

1:1-7 Nebuchadnezzar, king of Babylon, in the first year of his reign, took Jerusalem, and carried whom and what he pleased away. From this first captivity, most think the seventy years are to be dated. It is the interest of princes to employ wise men; and it is their wisdom to find out and train up such. Nebuchadnezzar ordered that these chosen youths should be taught. All their Hebrew names had something of God in them; but to make them forget the God of their fathers, the Guide of their youth, the heathen gave them names that savoured of idolatry. It is painful to reflect how often public education tends to corrupt the principles and morals.
