'House of the Lord' in the Bible

Sanctify a fast. Call a solemn assembly. Gather the elders, and all the inhabitants of the land, to the house of the LORD, your God, and cry to the LORD.

It will happen in that day, that the mountains will drop down sweet wine, the hills will flow with milk, all the brooks of Judah will flow with waters, and a fountain will come forth from the house of the LORD, and will water the valley of Shittim.
