Mark 13:23

"Ye therefore, beloved, seeing ye know these things before, beware lest ye also, being led away with the error of the wicked, fall from your own stedfastness."

"And he said, Take heed that ye be not deceived: for many shall come in my name, saying, I am Christ; and the time draweth near: go ye not therefore after them."

"And Jesus answering them began to say, Take heed lest any man deceive you:"

"And now I have told you before it come to pass, that, when it is come to pass, ye might believe."

"But take heed to yourselves: for they shall deliver you up to councils; and in the synagogues ye shall be beaten: and ye shall be brought before rulers and kings for my sake, for a testimony against them."

"Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves."

"And take heed to yourselves, lest at any time your hearts be overcharged with surfeiting, and drunkenness, and cares of this life, and so that day come upon you unawares."

"Take ye heed, watch and pray: for ye know not when the time is."
