'Myself' in the Bible

Then she continued talking with her father, "Do this for me: leave me alone by myself for two months. I'll go up to the mountains and cry there because I'll never marry. My friends and I will go."

When she cried out, "The Philistines are attacking you, Samson!" he woke from his sleep and told himself, "I'll go out like I did at other times like this and shake myself free." But he didn't know that the LORD had abandoned him.

Then Samson told the young man who had been leading him around by the hand, "Let me touch and feel the pillars on which this building rests, and I'll support myself against them."
