'Thus Says the Lord' in the Bible

"Go and tell my servant David, 'Thus says the LORD, "Shall you build me a house for me to dwell in?

Now therefore you shall tell my servant David this, 'Thus says the LORD of hosts, "I took you from the sheep pen, from following the sheep, that you should be prince over my people, over Israel.

"Go and speak to David, 'Thus says the LORD, "I offer you three things. Choose one of them, that I may do it to you."'"
