Welllll,
Not entirely sure what you mean.
As Tevya said . . . May the Lord Bless and keep the Tzar far away from him.
I can add all kinds of phrases after have a blessed sleep--such as with God giving you dreams and visions drawing you to Himself; showing you His truth; making Scripture and the truth of Jesus The Christ real to you . . . etc. without posting what I add to The Lord.
NIV Matthew 24:35
Heaven and earth will pass away, but my words will never pass away.
NIV 2 Peter 3:7
By the same word the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of ungodly men.
NIV 2 Peter 3:10-11
10. But the day of the Lord will come like a thief. The heavens will disappear with a roar; the elements will be destroyed by fire, and the earth and everything in it will be laid bare.
11. Since everything will be destroyed in this way, what kind of people ought you to be?
You ought to live holy and godly lives
12. as you look forward to the day of God and speed its coming. That day will bring about the destruction of the heavens by fire, and the elements will melt in the heat.
13. But in keeping with his promise we are looking forward to a new heaven and a new earth, the home of righteousness.
NIV Revelation 21:1
Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea.
