'Sins' in the Bible

please let Your ear be attentive and Your eyes open to hear the prayer of Your servant which I am praying before You, day and night, on behalf of Your servants, the sons (descendants) of Israel (Jacob), confessing the sins of the sons of Israel which we have committed against You; I and my father’s house have sinned.

The descendants of Israel (Jacob) separated themselves from all foreigners, and stood and confessed their sins and the wrongdoings of their fathers.

“Its abundant produce is for the kingsWhom You have set over us because of our sins;They also rule over our bodiesAnd over our cattle as they please,So we are in great distress.
