'Sinned' in the Bible

Who gave up Jacob [the kingdom of Judah] for spoil, and [the kingdom of] Israel to the plunderers?Was it not the Lord, He against whom we [of Judah] have sinned,And in whose ways they [of Israel] were unwilling to walk,And whose law and teaching they did not obey?

“Your first father [Jacob] sinned,And your spokesmen [the priests and the prophets—your mediators] have transgressed against Me.

You meet him who rejoices in doing that which is morally right,Who remembers You in Your ways.Indeed, You were angry, for we sinned;We have long continued in our sins [prolonging Your anger].And shall we be saved [under such circumstances]?
