The king answered and said, I know of certainty
I see plainly and clearly what you are at, and am fully assured you mean nothing, but that ye would gain the time:
or buy F6, or redeem time, as in ( Ephesians 5:16 ) , prolong time, put off the answer to longer time; spin out time, as people do in buying and selling; or have it in their possession and power when to answer; and so by gaining time, or being master of it, might hope something would turn up to their advantage, and extricate them out of their present difficulties: because ye see the thing is gone from me;
the dream he could not remember; or because the decree was certain which he had determined concerning them; (See Gill on Daniel 2:5).
