'Establish' in the Bible

All the presidents of the kingdom, the deputies and the satraps, the counselors and the governors, have consulted together to establish a royal statute, and to make a strong decree, that whoever shall ask a petition of any god or man for thirty days, except of you, O king, he shall be cast into the den of lions.

Now, O king, establish the decree, and sign the writing, that it not be changed, according to the law of the Medes and Persians, which doesn't alter.

In those times there shall many stand up against the king of the south: also the children of the violent among your people shall lift themselves up to establish the vision; but they shall fall.
