'Astray' in the Bible

What think ye? if a man may have an hundred sheep, and there may go astray one of them, doth he not -- having left the ninety-nine, having gone on the mountains -- seek that which is gone astray?

and if it may come to pass that he doth find it, verily I say to you, that he doth rejoice over it more than over the ninety-nine that have not gone astray;

And Jesus answering said to them, 'Ye go astray, not knowing the Writings, nor the power of God;

And Jesus answering said to them, 'Take heed that no one may lead you astray,

for many shall come in my name, saying, I am the Christ, and they 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 they shall give great signs and wonders, so as to lead astray, if possible, also the chosen.
