'Astray' in the Bible

How think ye? if any man have a hundred sheep, and one of them be gone astray, doth he not leave the ninety and nine, and go unto the mountains, and seek that which goeth astray?

And if so be that he find it, verily I say unto you, he rejoiceth over it more than over the ninety and nine which have not gone astray.

And Jesus answered and said unto them, Take heed that no man lead you astray.

For many shall come in my name, saying, I am the Christ; and shall lead many astray.

And many false prophets shall arise, and shall lead many astray.

For there shall arise false Christs, and false prophets, and shall show great signs and wonders; so as to lead astray, if possible, even the elect.
