Final answer:
A kingdom divided against itself faces internal conflict, leading to instability and vulnerability to external threats, which can result in its collapse. This historical pattern indicates that internal unity is crucial for a kingdom's survival and prosperity.
Step-by-step explanation:
If a kingdom is divided against itself, it is likely to face significant challenges that could ultimately lead to its downfall. History has shown that a lack of unity within a state can result in internal conflict, which weakens the kingdom's overall structure and stability. This can attract external threats, as adversaries may seek to take advantage of the internal discord.
For instance, after Solomon's death, the kingdom of Israel was split into two separate entities, causing a period of turmoil and weakening the former united monarchy. Biblical accounts suggest that the northern kingdom often levied undue influence or even waged war against the southern kingdom. Similarly, when an army is filled with distrust and restlessness, as indicated in the provided reference, it suggests impending trouble, likely stemming from other factions within the kingdom or state.
To avoid such a fate, leaders and generals are advised to act with caution, as illustrated in the texts, emphasizing that a previously destroyed kingdom cannot be restored to its former glory. History repeatedly demonstrates that a kingdom torn by internal strife has difficulty maintaining its sovereignty and risks falling into a state of anarchy, which could ultimately result in its collapse.
