'Unto' in the Bible

(and the life was manifested, and we have seen, and bear witness, and declare unto you the life, the eternal life , which was with the Father, and was manifested unto us);

that which we have seen and heard declare we unto you also, that ye also may have fellowship with us: yea, and our fellowship is with the Father, and with his Son Jesus Christ:

And this is the message which we have heard from him and announce unto you, that God is light, and in him is no darkness at all.

My little children, these things write I unto you that ye may not sin. And if any man sin, we have an Advocate with the Father, Jesus Christ the righteous:

Beloved, no new commandment write I unto you, but an old commandment which ye had from the beginning: the old commandment is the word which ye heard.

Again, a new commandment write I unto you, which thing is true in him and in you; because the darkness is passing away, and the true light already shineth.

I write unto you, my little children, because your sins are forgiven you for his name's sake.

I write unto you, fathers, because ye know him who is from the beginning. I write unto you, young men, because ye have overcome the evil one. I have written unto you, little children, because ye know the Father.

I have written unto you, fathers, because ye know him who is from the beginning. I have written unto you, young men, because ye are strong, and the word of God abideth in you, and ye have overcome the evil one.

I have not written unto you because ye know not the truth, but because ye know it, and because no lie is of the truth.

These things have I written unto you concerning them that would lead you astray.

And the witness is this, that God gave unto us eternal life, and this life is in his Son.

These things have I written unto you, that ye may know that ye have eternal life, even unto you that believe on the name of the Son of God.

If any man see his brother sinning a sin not unto death, he shall ask, and God will give him life for them that sin not unto death. There is a sin unto death: not concerning this do I say that he should make request.

All unrighteousness is sin: and there is a sin not unto death.
