2 Kings 7:9-11

Then they said one to another, We do not well: this day is a day of good tidings, and we hold our peace: if we tarry till the morning light, some mischief will come upon us: now therefore come, that we may go and tell the king's household. So they came and called unto the porter of the city: and they told them, saying, We came to the camp of the Syrians, and, behold, there was no man there, neither voice of man, but horses tied, and asses tied, and the tents as they were. And he called the porters; and they told it to the king's house within.
