'Myself' in the Bible

and I was blameless before him, and I kept myself from my guilt.

For {I myself know} my transgressions, and my sin [is] ever before me.

For [it is] not an enemy [that] taunts me, or I could bear [it]. [It is not] one who hates me [that] magnifies himself over me, or I could hide myself from him.

My heart is not haughty nor my eyes {arrogant}. And I do not {concern myself} with things too great and difficult for me.
