Watch your thoughts; they become words.
Watch your words; they become actions.
Watch your actions; they become habits.
Watch your habits; they become character.
Watch your character; it becomes your destiny.

But I will defend my house [realm of responsibility, family, home, God-given appointment]

against marauding [evil, destroying]  forces.

Never again will an oppressor overrun my people,

for now I am [keenly aware, eyes wide open, warily prepared] keeping watch.

  Zechariah 9.8
