'Signs' in the Bible

for there shall rise false Christs and false prophets, and they shall give signs and wonders, to seduce, if possible, also the chosen;

'And signs shall accompany those believing these things; in my name demons they shall cast out; with new tongues they shall speak;

and they, having gone forth, did preach everywhere, the Lord working with them, and confirming the word, through the signs following. Amen.
