'Tranquility' in the Bible

In his place a despicable person will arise, on whom the honor of kingship has not been conferred, but he will come in a time of tranquility and seize the kingdom by intrigue.

In a time of tranquility he will enter the richest parts of the realm, and he will accomplish what his fathers never did, nor his ancestors; he will distribute plunder, booty and possessions among them, and he will devise his schemes against strongholds, but only for a time.
