'Myself' in the Bible

I was also blameless with Him,And I kept myself from my iniquity.

For it is not an enemy who reproaches me,Then I could bear it;Nor is it one who hates me who has exalted himself against me,Then I could hide myself from him.

I have remembered Your ordinances from of old, O Lord,And comfort myself.

A Song of Ascents, of David.O Lord, my heart is not proud, nor my eyes haughty;Nor do I involve myself in great matters,Or in things too difficult for me.
