'Astray' in the Bible

"What do you think? If a man has one hundred sheep, and one of them goes astray, doesn't he leave the ninety-nine, go to the mountains, and seek that which has gone astray?

If he finds it, most certainly I tell you, he rejoices over it more than over the ninety-nine which have not gone astray.

Jesus answered them, "Be careful that no one leads you astray.

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

Many false prophets will arise, and will lead many astray.

For there will arise false christs, and false prophets, and they will show great signs and wonders, so as to lead astray, if possible, even the chosen ones.
