'Hereby' in the Bible

For I know nothing against myself; yet am I not hereby justified: but he that judgeth me is the Lord.

And hereby we know that we know him, if we keep his commandments.

but whoso keepeth his word, in him verily hath the love of God been perfected. Hereby we know that we are in him:

Hereby know we love, because he laid down his life for us: and we ought to lay down our lives for the brethren.

Hereby shall we know that we are of the truth, and shall assure our heart before him:

And he that keepeth his commandments abideth in him, and he in him. And hereby we know that he abideth in us, by the Spirit which he gave us.

Hereby know ye the Spirit of God: every spirit that confesseth that Jesus Christ is come in the flesh is of God:

hereby we know that we abide in him and he in us, because he hath given us of his Spirit.

Hereby we know that we love the children of God, when we love God and do his commandments.
