'House of God' in the Bible

These things I remember and I pour out my soul within me.For I used to go along with the throng and lead them in procession to the house of God,With the voice of joy and thanksgiving, a multitude keeping festival.

But as for me, I am like a green olive tree in the house of God;I trust in the lovingkindness of God forever and ever.

We who had sweet fellowship togetherWalked in the house of God in the throng.
