'Myself' in the Bible

I will stand at my guard postand station myself on the lookout tower.I will watch to see what He will say to meand what I should reply about my complaint.

When I heard, my belly trembled; my lips quivered at the voice: rottenness entered into my bones, and I trembled in myself, that I might rest in the day of trouble: when he cometh up unto the people, he will invade them with his troops.
