'Establish' in the Bible

All of [the] administrators of the kingdom, and the prefects, the satraps, the counselors and the governors took counsel [and have] agreed to establish an edict of the king and to enforce a decree that {whoever} will seek a prayer from any god or human except from you [for] up to thirty days will be thrown into {the lion pit}.

Now, O king, establish the edict and you must sign the document [so] that [it] cannot be changed, according to [the] law of [the] Medes and Persians which cannot be revoked."
