Matthew 24:4, 5, 12, 36-39

24:4  And Jesus answered and said unto them, Take heed that no man deceive you.

24:5  For many shall come in my name, saying, I am Christ; and shall deceive many.

24:12  And because iniquity shall abound, the love of many shall wax cold.

24:24  For there shall arise false Christs, and false prophets, and shall show great signs and wonders; insomuch that, if [it were] possible, they shall deceive the very elect.

24:36  But of that day and hour knoweth no [man], no, not the angels of heaven, but my Father only.

24:37  But as the days of Noe [were], so shall also the coming of the Son of man be.

24:38  For as in the days that were before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noe entered into the ark,

24:39  And knew not until the flood came, and took them all away; so shall also the coming of the Son of man be.
