Charles Spurgeon Commentary 1 Kings 20:5-6

"And the messengers came again, and said, Thus speaketh Ben-hadad, saying, I sent indeed unto thee, saying, Thou shalt deliver me thy silver, and thy gold, and thy wives, and thy children; but I will send my servants unto thee to-morrow about this time, and they shall search thy house, and the houses of thy servants; and it shall be, that whatsoever is pleasant in thine eyes, they shall put it in their hand, and take it away." — 1 Kings 20:5-6 (ASV)

That is always the way with such people: give them an inch, and they take a mile. Ahab had agreed to all that the Syrian king claimed, so now Benhadad pushes his advantage.

If you ever yield to Satan, you will find him to be a hard taskmaster. You can never yield enough to satisfy him. And if you yield to any sin, whatever it may be, you will find it to be a cruel tyrant to you. If you allow it once to have power over your soul, it will push its advantage further and further and make your yoke exceedingly heavy.
