'Unto' in the Bible

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

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

And these things write we unto you, that your joy may be full.

This then is the message which we have heard of him, and declare 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 sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:

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

Again, a new commandment I write unto you, which thing is true in him and in you: because the darkness is past, and the true light now shineth.

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

I write unto you, fathers, because ye have known him that is from the beginning. I write unto you, young men, because ye have overcome the wicked one. I write unto you, little children, because ye have known the Father.

I have written unto you, fathers, because ye have known him that 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 wicked one.

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

These things have I written unto you concerning them that seduce you.

We know that we have passed from death unto life, because we love the brethren. He that loveth not his brother abideth in death.

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

If any man see his brother sin a sin which is not unto death, he shall ask, and he shall give him life for them that sin not unto death. There is a sin unto death: I do not say that he shall pray for it.

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