'Remember' in the Bible

Therefore, remember from what high state you have fallen and repent! Do the deeds you did at the first; if not, I will come to you and remove your lampstand from its place -- that is, if you do not repent.

Therefore, remember what you received and heard, and obey it, and repent. If you do not wake up, I will come like a thief, and you will never know at what hour I will come against you.
