'In Me' in the Bible

Then he said, The Lord is witness against you, and the man on whom he has put the holy oil is witness this day that you have seen no wrong in me. And they said, He is witness.

Then Saul said to the Lord, the God of Israel, Why have you not given me an answer today? If the sin is in me or in Jonathan my son, O Lord God of Israel, give Urim, and if it is in your people Israel, give Thummim. And by the decision of the Lord, Saul and Jonathan were marked out, and the people went free.

So, then, be kind to your servant; for you have been united with your servant in an agreement made before the Lord: but if there is any wrongdoing in me, put me to death yourself; why take me to your father?

And he said, Why does my lord go armed against his servant? what have I done? or what evil is there in me?
