2 Peter 3:8-10

Young's Literal Translation

⁸ And this one thing let not be unobserved by you, beloved, that one day with the Lord [is] as a thousand years, and a thousand years as one day;

⁹ the Lord is not slow in regard to the promise, as certain count slowness, but is long-suffering to us, not counselling any to be lost but all to pass on to reformation,

¹⁰ and it will come -- the day of the Lord -- as a thief in the night, in which the heavens with a rushing noise will pass away, and the elements with burning heat be dissolved, and earth and the works in it shall be burnt up.
