By "house" you can understand not only the temple, but also the entire Jewish race. For Scripture sometimes calls a race a house as well, for example: "O house of Levi, bless the Lord" (Ps. 134:20). Since here too it can be understood thus: "house," that is, your race, is being left by Me. Just as in another place He says through the prophet: I have forsaken My house, I have abandoned My heritage. Here the Israelites are called a house. The Lord shows that even before this it was He who preserved them and delivered them from enemies.
Lk. 13:35. I tell you, you will not see Me until the time comes when you will say: Blessed is He who comes in the name of the Lord!
The words point to the second coming. For then, even against their will, they will confess Him as Savior and Lord. Only it will be of no benefit to them. What then? Did they really not see Him from the time He said this? Exactly so. When He says "you will not see Me" from now on, He does not indicate immediately, but the time after the cross. He spoke as if to say: from the time you crucify Me, you will no longer see Me, until I come a second time.
