'Dear' in the Bible

Dear friends, this is now the second letter I have written to you; in both letters, I want to develop a genuine understanding with a reminder,

Dear friends, don’t let this one thing escape you: With the Lord one day is like a thousand years, and a thousand years like one day.

Therefore, dear friends, while you wait for these things, make every effort to be found at peace with Him without spot or blemish.

Also, regard the patience of our Lord as an opportunity for salvation, just as our dear brother Paul has written to you according to the wisdom given to him.

Therefore, dear friends, since you know this in advance, be on your guard, so that you are not led away by the error of lawless people and fall from your own stability.
