Daniel 6:14

Then the king, when he heard these words, was sore displeased
with himself
Or "at it" ^F5; or "with him"; with Daniel, not so much for what he had done, but that he had not done it with more caution, or more privately, that it might not have been known: or rather, as we render it, "with himself", that he should so rashly sign the decree, without considering the consequences of it; for he now found that he was circumvented by his princes, and that their design was not his honour and glory, but the destruction of Daniel: or the sense in general is, that what he heard was very disagreeable, afflictive, and distressing to him: and set his heart on Daniel to deliver him;
he resolved, if possible, to do it; he applied his mind to it; he turned his thoughts wholly that way, and contrived all ways and means to effect it: R. Mattathiah, in Saadiah, interprets the phrase of his offering money as a ransom for his life: and he laboured till the going down of the sun to save him;
from the will of the princes, and from the jaws of the lions: very probably it was early in the morning these princes found Daniel at prayer, who went immediately to the king with their accusation; so that he was all day labouring with all his might and main to find out ways and means to save his darling favourite; he studied to put such a sense upon his decree, that it might not reach Daniel's case; he strove to make the princes easy, and to persuade them to drop the affair, and not insist on the execution of the decree.
