LEV71 We must not cause someone embarrassment by referring to his past misdeeds. The Talmud (Yerushalmi Yevomos 8:3) explains that the reason the sin offering and burnt offering were slaughtered in the same place in the Sanctuary was to save sinners from embarrassment. Anyone witnessing someone bringing a sin offering could assume that it was a burnt offering which is brought as a donation and not necessarily as an atonement for a transgression. Using this as a source, the Sages made a regulation that prayer (shmoneh esrai) must be recited quietly in order not to embarrass people who confess their sins during their prayers. (Sotah 32b). This verse teaches us that we must be very careful not to cause someone embarrassment or discomfort because of past misdeeds.
