'Do Not Forget' in the Bible

Do not forget to show hospitality toward strangers, for by doing this, some people have entertained angels without realizing it.

But do not forget to do good deeds and share [with others], for God is very pleased with such "sacrifices."

But do not forget this one thing, my dearly loved ones, that as the Lord [counts time], one day is like a thousand years, and a thousand years are like one day.
