חָתֻ֣ם בִּצְר֣וֹר פִּשְׁעִ֑י וַ֝תִּטְפֹּ֗ל עַל־עֲוֺנִֽי׃
a minha transgressão estaria selada num saco, e ocultarias a minha iniqüidade.
Rashi
Willful sinners have heaped false accusations upon me Heb. טפלו, they joined upon me, and similarly (Job 14:17): “and You have attached Yourself (ותטפל) to my iniquity.”
