Proverbs (Mishlei) 30
6 Do not add to His Words, Lest He reprove you, and you be found a liar.
1 John (Yokhanan Alef) 1
6 If we say that we have fellowship with Him and yet live in darkness, we lie and do not follow the truth; 7 But if we live in the light as He is in the light, we have fellowship with one another and the blood of Yeshua his Son cleanses us from all sin. 8 If we say that we have no sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all our unrighteousness. 10 If we say that we have not sinned, we make him a liar and his word is not in us.
1 John (Yokhanan Alef) 2
1 MY little children, these things I write to you that you do not sin. 2 And if any man sin, we have an advocate with the Father, Yeshua HaMashi’akh the righteous; And he is the propitiation for our sins; and not for ours only but also for the sins of the whole world. 3 And hereby we know that we know him, if we keep his commandments.
Revelation (Hitgalut) 22
18 I testify to everyone hearing the words of the prophecy of this book: If anyone adds to them, may Elohim add to him the plagues are written in this book,
19 And if anyone takes away from the words of the book of this prophecy, may Elohim take away his part from the Book of Life, and out of the set-apart city, which are written in this Book.
