Daniel 6:14-15

Daniel had so won the king’s favor that Darius immediately and energetically began trying to rescue his friend. Nebuchadnezzar had become angry with Daniel’s three friends when they refused to idolize him (Daniel 3:19), but Darius became angry with himself for signing the decree (cf. Daniel 2:1; Daniel 3:13; Daniel 5:6; Daniel 5:9). This shows how much he respected and valued Daniel.
