Deuteronomy 19:15-20

The wisdom of those laws is too obvious to need a comment; they have been already noticed: Numbers 35:30. But what a sweet thought is it to the believer's experience, that in divine things there are the Holy Three which bear record in heaven, and there is the evidence of three which carry a corresponding testimony to his heart; namely, the HOLY GHOST as the first great witness in the spirits of his people; his sacred word as the second; and the believer's heart as the third, in which the evidence is given; and all these three agree in one, in their united testimony to the truth as it is in JESUS. 2 Corinthians 13:1.
