Doth our law judge any man, before it hear him, and know what he doeth?
Deuteronomy 1:17
Ye shall not respect persons in judgment; but ye shall hear the small as well as the great; ye shall not be afraid of the face of man; for the judgment is God's: and the cause that is too hard for you, bring it unto me, and I will hear it.
Deuteronomy 17:8-11
8
If there arise a matter too hard for thee in judgment, between blood and blood, between plea and plea, and between stroke and stroke, being matters of controversy within thy gates: then shalt thou arise, and get thee up into the place which the LORD thy God shall choose;
9
And thou shalt come unto the priests the Levites, and unto the judge that shall be in those days, and enquire; and they shall shew thee the sentence of judgment:
10
And thou shalt do according to the sentence, which they of that place which the LORD shall choose shall shew thee; and thou shalt observe to do according to all that they inform thee:
11
According to the sentence of the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the sentence which they shall shew thee, to the right hand, nor to the left.
Deuteronomy 19:15-19
15
One witness shall not rise up against a man for any iniquity, or for any sin, in any sin that he sinneth: at the mouth of two witnesses, or at the mouth of three witnesses, shall the matter be established.
16
If a false witness rise up against any man to testify against him that which is wrong;
17
Then both the men, between whom the controversy is, shall stand before the LORD, before the priests and the judges, which shall be in those days;
18
And the judges shall make diligent inquisition: and, behold, if the witness be a false witness, and hath testified falsely against his brother;
19
Then shall ye do unto him, as he had thought to have done unto his brother: so shalt thou put the evil away from among you.
Proverbs 18:13
He that answereth a matter before he heareth it, it is folly and shame unto him.
