'Sin' in the Bible

So all Israel was enrolled in genealogy. And behold, they were written in the book of the kings of Israel. And Judah was taken away to Babylon on account of their sin.

So Saul died on account of his sin which he had sinned against Yahweh concerning the command of Yahweh that he did not keep. He also consulted a medium to seek [guidance].

Then David said to God, "I have sinned severely [in] that I have done this thing. But now, please forgive the sin of your servant, for I have been very foolish."
