Musar do Malachiasza 1:10

Modesty is indeed a good quality and is the opposite of arrogance. And he who possesses this quality has already turned away his soul from all sorts of evils, and he who has reached this honored lofty degree performs a precept and receives his reward according to the greatness of his humility. For Modesty is the root of Service to God, and a small deed done with Modesty is received by God, Blessed be He, a thousand times more readily than a great deed performed with arrogance. And thus did our Sages say: "The one who sacrifices much and the one who sacrifices little have the same merit, provided that the heart is directed to heaven" (Berakoth 5b Menahoth, 110:a). But a work done with arrogance is not welcomed by God, Blessed be He, for it is an abomination to His Spirit, as it is said: "Every one that is proud in heart is an abomination to the Lord" (Proverbs 16:5). "And because of this he cries and is not answered, as it is said: "Yea, when ye make many prayers I will not hear" (Isaiah 1:15). And a man of arrogance may perform the precepts and they tear them to pieces before his eyes, as it is said: "Oh, that there were even one among you that would shut the doors (of the Temple so that the arrogant would not presume to serve Me!)" (Mal. 1:10). And when an arrogant person brings a sacrifice it is not received, as it is said: "Who hath required this at your hands, to trample My courts?" (Is. 1:12). And, it is said: "Add your burnt offerings unto your sacrifices and eat ye flesh" (Jer. 7:21). (That is to say. "Don't offer your burnt offerings to Me; I do not want them.")

How excellent is the quality of repentance. Last night this one was separated from the Lord, the God of Israel, Blessed be He. As it is said, "But your iniquities have separated between you and your God" (Is. 59:2). He cried and he was not answered, as it is said, "Yea, when ye make many prayers, I will not hear" (Is. 1:15). And he fulfilled precepts and they were torn up before his face, as it is said, "Who hath required this at your hand, to trample my courts" (Is. 1:12), and, "Oh that there were even one among you that would shut the doors" Mal. 1:10), and, "Hold your burnt offerings unto your sacrifices and eat ye flesh" (Jer. 7:21). Yet today he is closely attached to the Divine Presence, as it is said, "But you, who hold fast to the Lord your God" (Deut. 4:4). He cries out and is answered at once, as it is said, "And it shall come to pass that, before they call, I will answer" (Is. 65:24). He fulfills the commandments and they are received with pleasure and with joy, as it is said, "For the Lord hath already accepted thy works" (Eccl. 9:7). Moreover, his commandments are desired, as it is said, "Then shall the offering of Judah and Jerusalem be pleasant unto the Lord, as in days of old and in ancient years" (Mal. 3:4).
