... And the intention of the matter is, Binah set up an arranged all the matters/things in the manner of truth and judgement and the kingship/government (in context, court) of the firmament (arguably heavens, but *not* shamayim. Rakia is typically translated as firmament I believe) is like the kingship/government of the Earth. Even though the Binah truly knows the truth, it will not judge without a plaintiff and witnesses.
And it, in this form, the Binah appoints a litigator/a plaintiff, which is the Satan, to litigate the judgement from the people of the world. And the witnesses are the eyes of Hashem, which see and watch over the actions of people hidden and visible. (Here, Sefirah Binah appears to refer to Hashem's ideation, as distinct from God's eyes, meaning vision). This is what Chazal said, "If someone is to commit an aveira in secret, the beams of his house testify against him." These are the eyes of Hashem. The beams of the crown and strengthening.(Heb. unclear)
