Proverbs 30:5 KJV
Every word of God is pure: he is a shield unto them that put their trust in him.
Galatians 1:6-9 KJV
[6] I marvel that ye are so soon removed from him that called you into the grace of Christ unto another gospel:
[7] Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
[8] But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.
[9] As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
(II Corinthians 11:1-8 [KJV])
[1] Would to God ye could bear with me a little in my folly: and indeed bear with me.
[2] For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
[3] But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.
[4] For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
[5] For I suppose I was not a whit behind the very chiefest apostles.
[6] But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.
[7] Have I committed an offence in abasing myself that ye might be exalted, because I have preached to you the gospel of God freely?
[8] I robbed other churches, taking wages of them, to do you service.
