Le temps est venu d’agir pour l’Éternel: on a violé ta Loi.
Rabbeinu Yonah
and received the reward of them all: And even though there is a portion in the Garden of Eden and a portion in Gehinnom for every person - if he merits [it], he takes his portion in the Garden of Eden; and if he is guilty in his judgement, he takes it in Gehinnom - nonetheless, since everyone is commanded to do good and this one does not do [it] and his fellow fulfills his commands and his own commands; the trait of justice would indicate that he should take his portion and the portion of his fellow in the Garden of Eden. And for this [reason] did our father, Avraham take the reward of all of them. And this is what is stated (Psalms 119:126), "It is a time to act for the Lord, for they have violated Your Torah" - if you see a generation that is negligent from [study] of the Torah, be involved in it (Berakhot 63a). And the simple meaning of the verse is "It is a time to act for the sake of the Lord." And similar to it is (Genesis 20:13), "say for me, 'He is my brother'" - [which is] like "for my sake." "They have violated your Torah" - since they are all violating Your Torah, I should do for the sake of the Lord more than in other generations, so that Torah is not, God forbid, forgotten in Israel. There is a parable [relevant to this] about a king whom all of his servants betrayed except for one. Does [that servant] not need to go with him truthfully and with a whole heart at that time more than other times? And so all of his days the king will love him with a great love and increase his gift [to be] equal to the gifts of all of them [together].

to establish times Heb. לָעוּת. Menahem classified it in the group of (Ps. 119:126) “It is time (עֵת) to do for the Lord.” To establish times for them.
Rabbeinu Yonah
In a place where there is no man, strive to be a man: The early scholars (rishonim) explained, "In a place where there is no man" to help you in the commandments and to chastise you, "strive to be a man" and straighten yourself, so as to only 'do that which is good and straight in the eyes of the Lord.' Another explanation: "In a place where there is no man" - if you see a generation wherein the Torah is slacking, stand up and strive with it, as it is stated (Psalms 119:126), "It is a time to do for the Lord, they have abrogated your Torah." What is the reason that "it is a time to do for the Lord?" Because "they have abrogated your Torah" - as its beginning is learned from its end - as it is found at the end of Tractate Berakhot 63a. And we can also explain, "In a place where there is no man" greater than you in wisdom, "strive to be a man." And do not refrain from becoming wiser, even if you cannot find a sage greater than you in your city. Even if there is no one like you in that [whole] generation, see yourself as [if you were] in the generation of the sages of the Talmud and you are with them in one place. Even if you acquire their level, think as if you are standing with the prophets, up until Moshe, our teacher - peace be upon him. And when will you reach their level and their wisdom? And in this [way], you will never slack from learning Torah and you will improve your traits each and every day - as you will add to your wisdom and you will be like a flowing spring.
