Deuteronomy 17:8

If there be with you an extraordinary matter for judgment between unclean and clean blood, cases of life or of money, or between a plague of leprosy or of the scall, with words of controversy in your beth din, then you shall arise and go up to the place which the Lord your God will choose;

Should something be too difficult for you Scripture here addresses the judge. The sense of the verse is: “If it be still hard to decide, after receiving the testimony of the two witnesses, whether to execute the accused…” (this is the meaning of between blood and blood: to decide whether the execution would be an act of innocent bloodshed, or culpable bloodshed).

The word difficult appears also in the phrase “is anything too difficult for God ?” [Genesis 18: 14], where it is explained [comment on Genesis 18: 14].

between judgment and judgment monetary matters.

between injury and injury cases of wounding and battery.

Controversial matters is the inclusive category. I have already explained the terms you must get up, and ascend [commentary on Numbers 16: 12].

IF THERE ARISE A MATTER TOO HARD FOR THEE IN JUDGMENT, BETWEEN BLOOD AND BLOOD, BETWEEN PLEA AND PLEA, AND BETWEEN PLAGUE AND PLAGUE, MATTERS OF CONTROVERSY WITHIN THY GATES. “Matters of controversy — if the Sages of the city disagree over the matter, this one declaring it unclean and that one declaring it clean, this one convicting and that one acquitting.” This is Rashi’s language. It is also the opinion of Onkelos [who translated: matters of controversy — “disagreement among the judges”]. But it is not correct. refers back to between blood and blood etc. Ramban will explain matters of controversy as an independent expression, as explained further on. Rather, according to the Midrash thereof 152. Sanhedrin 87a. it means as follows: “Between blood and blood, [the Sages disagree whether the blood in question is clean or unclean, the blood being any of the following]: the blood of a menstruous woman, the blood of a woman in childbirth, or the blood of a woman suffering a flux. Between plea and plea, [they disagree concerning the verdict in] civil cases, capital cases, and laws of scourging. And between plague and plague, [concerning] plagues of man, plagues of houses, and plagues of garments. Matters of controversy, giving the water to a suspected adulteress, the breaking of the heifer’s neck, and the purifying of the leper.” Thus the meaning of the word between [‘between’ blood and blood] is “and between,” [the verse stating: If there arise a matter too hard for thee in judgment, “and” between blood and blood, since the phrase between blood and blood is a new category, and not in apposition to the first part of the verse]. The letter lamed [in the words l’dam which literally means “in regard to blood” and l’din — “in regard to a plea”] has the usage here of a beth [meaning “among”], “between blood ‘among’ blood, plea ‘among’ pleas,” meaning, should a case arise concerning one [form of blood] among the various forms of blood, or concerning one [plea] among the various pleas, [a case that will be too difficult for you to decide]. A similar usage [of a lamed serving as beth is found in these verses:] but the name of the city was Luz ‘larishonah’ [literally: “‘to’ the beginning”] means barishonah — “in the beginning;” the Eternal smote him in his bowels ‘lacholi l’ein marpei’ [literally: “to an …

כי יפלא ממך, even though you have appointed competent judges in each town and city, in order that each court would dispense justice in its home base, if a doubt arises as to what the correct ruling is according to reliable tradition, the local court is not to hand down a ruling according to their opinion when it is not supported by authentic tradition, but the problem should be submitted to the Supreme Court, Sanhedrin. The same holds true when the judges in the local court were deadlocked.
