'Remember' in the Bible

Remember therefore whence thou art fallen, and repent and do the first works; or else I come to thee, and will move thy candlestick out of its place, except thou repent.

Remember therefore how thou hast received and didst hear; and keep it , and repent. If therefore thou shalt not watch, I will come as a thief, and thou shalt not know what hour I will come upon thee.
