The passage teaches that when the attribute of justice prosecutes against Israel, angels in a known chamber present the acts of kindness that Israel performs in this world, causing God to have mercy upon them despite their liability; Ramak illustrates this through the destruction of the Temple, where God told Gabriel (the minister of judgment) that because Israel was performing acts of kindness toward one another, they would be saved and a remnant would remain, since God desires kindness.

The sixth: "For He is One that desires kindness" - did we not already explain in its place that in the known chamber, there are angels appointed to receive the bestowing of kindness that a man does in this world? And when the trait of justice prosecutes against Israel, these angels immediately show this kindness, and the Holy One, blessed be He, has mercy upon Israel, since He desires kindness. And even with their being liable, if they bestow kindness - this one to that one - He has mercy upon them. And it is like it was at the time of the destruction [of the Temple]: That it was told to Gavriel (Ezekiel 10:2), "Go inside the wheelwork, etc." - as he is the minister of judgement and power; and He gave him authority to receive powers of judgement, inside the wheelwork from under the cherubs, from the fire of the altar. This is the judgement of the power of kingship (malkhut). And the judgement was intensified until it sought to finish everything off - to uproot the seed of Israel, since they were liable for destruction. And it is written (Ezekiel 10:8), "And by the cherubs there appeared the form of the hand of a man under their wings." And this is [meaning] that the Holy One, blessed be He, said to Gavriel, "They are bestowing acts of kindness - these with those - and even if they are liable, they are saved and there shall be a remnant from them." And the reason is because of this trait - since He is One who desires kindness, He desires that which Israel does kindness. And He recalls that side for them, even as they are not fitting from another side. The seventh: "He will again have mercy on us" - behold, the Holy One, blessed be He, does not follow the trait of flesh and blood. [That trait is that] if [someone] angers him - if he is appeased from him, he is a little appeased, [but] not like the previous love [he had for him]. But if a person sinned [to God] and he repents, his stature is greater with the Holy One, blessed be He, [than before]. And this is [the meaning of] "In the place that penitents stand, [even] completely righteous ones cannot stand" (Berakhot 34b). And the reason is like they explained in the chapter [entitled] HaBoneh (it is in Menachot 29b in our texts) regarding why [the letter,] hey is made like a portico: "Such that the one that wants to exit from his world [may] exit." The explanation is that the world was created with a hey. And the Holy One, blessed be He, created the world widely open to the side of evil and sin. There is no side that does not have physicality, the evil impulse and defect - like a type of portico. It does not have fences but rather has a large breach, open towards the side of evil, to the bottom side. How many openings are there for anyone who wants to exit from his world - he cannot turn to a side that he will not find a side of sin and iniquity to go out to the external forces (chitsonim)! But it is [also] open from above; so that if he repents, he will be accepted. And they asked, "Let him be taken back through [the bottom]!" [They answered,] "the matter will not help." They [meant] with this that one who repents will not suffice to be fenced from iniquity [with a fence] like the fence of the righteous ones - since they did not sin, a small fence suffices for them. However, a small fence will not suffice for the sinner that sinned and repented. Rather, he needs to fence himself with several difficult fences, since he already breached the small fence once. If he approaches there, his impulse seduces him easily. Rather he needs to distance himself with a very great distancing. And for this [reason], he does not enter through the opening of the portico, where the breach is there. Rather, he ascends and enters through the small opening, [such that] he makes several difficulties and mortifications for himself and [thereby] closes the breaches.
