'Establish' in the Bible

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

Now, O king, establish the interdict, and sign the writing, that it be not changed, according to the law of the Medes and Persians, which altereth not.

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