'Strengthen' in the Bible

Taken counsel have all the presidents of the kingdom, the prefects, and the satraps, the counsellors, and the governors, to establish a royal statute, and to strengthen an interdict, that any who seeketh a petition from any god and man until thirty days, save of thee, O king, is cast into a den of lions.

and receive the kingdom do the saints of the Most High, and they strengthen the kingdom unto the age, even unto the age of the ages.
