Daniel 1:7

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.
