Hereby ye shall be proved: By the life of Pharaoh ye shall not go forth hence, except your youngest brother come hither.

And the man, the lord of the country, said unto us, Hereby shall I know that ye are true men; leave one of your brethren here with me, and take food for the famine of your households, and be gone:

And Moses said, Hereby ye shall know that the LORD hath sent me to do all these works; for I have not done them of mine own mind.

And Joshua said, Hereby ye shall know that the living God is among you, and that he will without fail drive out from before you the Canaanites, and the Hittites, and the Hivites, and the Perizzites, and the Girgashites, and the Amorites, and the Jebusites.

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

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

But whoso keepeth his word, in him verily is the love of God perfected: hereby know we that we are in him.

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

And hereby we know that we are of the truth, and shall assure our hearts before him.

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

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

We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.

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