23Let us hold fast the confession of our expectation without yielding, for He who promised is trustworthy.

24And let us be concerned for one another in order to stir up love and good works,a

25not forsaking the assembling of ourselves together, as is the habit of some, but encouraging, and so much more as you see the Day coming near.
Hebrews 10

10But the day of יהוה shall come as a thief in the night, in which the heavens shall pass away with a great noise, and the elements shall melt with intense heat, and the earth and the works that are in it shall be burned up.

11Seeing all these are to be destroyed in this way, what kind of people ought you to be in set-apart behaviour and reverence,
2 Peter 3
