1 Kings 20:24

And do this thing
Also take this further piece of advice:

take the kings away, every man out of his place:
for being brought up delicately, they were not inured to war, nor expert in the art of it; and being addicted to pleasure, gave themselves to that, and drew the king into it, which they observed was the case before, though they did not care to mention it; and if they were tributaries or allies, they would not fight as men do for their own country:

and put captains in their rooms;
of his own people, men of skill and courage, and who would fight both for their own honour, and for the good of their country.
