Daniel 1:7

1:7 But the overseer of the court officials renamed them. He gave ¹  Daniel the name Belteshazzar, Hananiah he named Shadrach, Mishael he named Meshach, and Azariah he named Abednego. ² 

Daniel 1:11

1:11 Daniel then spoke to the warden ³  whom the overseer of the court officials had appointed over Daniel, Hananiah, Mishael, and Azariah:

Daniel 3:12

3:12 But there are Jewish men whom you appointed over the administration of the province of Babylon – Shadrach, Meshach, and Abednego – and these men ⁴  have not shown proper respect to you, O king. They don’t serve your gods and they don’t pay homage to the golden statue that you have erected.”

[1:7]  ¹ tc The LXX and Vulgate lack the verb here.

[1:7]  ² sn The meanings of the Babylonian names are more conjectural than is the case with the Hebrew names. The probable etymologies are as follows: Belteshazzar means “protect his life,” although the MT vocalization may suggest “Belti, protect the king” (cf. Dan 4:8); Shadrach perhaps means “command of Aku”; Meshach is of uncertain meaning; Abednego means “servant of Nego.” Assigning Babylonian names to the Hebrew youths may have been an attempt to erase from their memory their Israelite heritage.

[1:11]  ³ sn Having failed to convince the overseer, Daniel sought the favor of the warden whom the overseer had appointed to care for the young men.

[3:12]  ⁴ sn Daniel’s absence from this scene has sparked the imagination of commentators, some of whom have suggested that perhaps he was unable to attend the dedication due to sickness or due to being away on business. Hippolytus supposed that Daniel may have been watching from a distance.
