God's calendar starts with darkness, not with light. This is why the Jews reckon the beginning of the day at sundown, not daybreak, as God spoke in Genesis chapter 1. I wish that they would reckon the year as beginning at the 1st passover as God has commanded, but they've always had trouble with obedience.
BTW, when the Lord talks about a house, he could be speaking of a structure, or he could be speaking of a people, or a family. His use of terms are broader than hours. Eventually the curse will consume the whole earth if men don't take the things that they see to heart. Prophecy is light from a dark place and even the NT prophets have written things which obviously were not true in their time though they anticipated them. I don't understand everything that the Lord is doing, I just say what He gives me to say and do what he gives me to do. If I am a false prophet as mr. BOL asserts, then I can tell you that according to scripture I was still sent by the Lord, but I don't think that's the case.
