'House of the Lord' in the Bible

And on hearing it Hezekiah took off his robe and put on haircloth and went into the house of the Lord.

And Hezekiah took the letter from the hands of those who had come with it; and after reading it, Hezekiah went up to the house of the Lord, opening the letter there before the Lord,

O Lord, quickly be my saviour; so we will make my songs to corded instruments all the days of our lives in the house of the Lord.

And Hezekiah said, What is the sign that I will go up to the house of the Lord?

And they will take your countrymen out of all the nations for an offering to the Lord, on horses, and in carriages, and in carts, and on asses, and on camels, to my holy mountain Jerusalem, says the Lord, as the children of Israel take their offering in a clean vessel into the house of the Lord.
