Génesis 20:6 Halajá: Sefer Chasidim

If an individual stood steadfast in a meritorious deed let him not boast of it saying, “How pious I am.” But rather let him offer praise and thanks to the Lord, praised and exalted be His fame, Who has rescued him from sinning before Him, who has it in His power to incline the heart to all that He desires, as it is written, “ The king’s heart is in the hand of the Lord as the watercourses” (Prov. 21:1). And he says, “and I also withheld thee from sinning against Me” (Gen. 20:6). Each one who wishes to return in repentance and achieve a status of piety and fathom the depths of God’s law, the depths of His glory, let him not enter (attempt to do so) except if he be discerning and a soul of goodwill without anger. Let him forsake converse with people and playing with children,¹Aboth 3:14. also converse with his wife except during coitus.²Hagigah 5b. And let him be as careful in the observance of a light command as a more serious command,³Aboth 2:1. and on guard to rise before an elder even a hundred times. And let this not be as a burden upon him because of his love for the Creator.
