DEUT939 We must do chesed every single day of our lives. The Chafetz Chayim notes that the Torah stresses that we must walk in God's ways all the days. The Sages explain that walking in God's ways means that we must emulate Him by bestowing kindness and being compassionate. Some people mistakenly think that if they do someone a favor, especially a major one, they have fulfilled their obligation to do chesed for the next few weeks. Therefore, the Torah stresses that the obligation of chesed is all the days. Every single day of our lives we must go out of our way do someone a favor. (Ahavas Chesed, ch. 12)
