1 Corinthians 12:1-3

Darby(i) 1 But concerning spiritual [manifestations], brethren, I do not wish you to be ignorant. 2 Ye know that when ye were [of the] nations [ye were] led away to dumb idols, in whatever way ye might be led. 3 I give you therefore to know, that no one, speaking in [the power of the] Spirit of God, says, Curse [on] Jesus; and no one can say, Lord Jesus, unless in [the power of the] Holy Spirit.
