'Myself' in the Bible

And there came a man of God to Eli and said to him, Thus saith Jehovah: Did I plainly reveal myself to the house of thy father when they were in Egypt, in Pharaoh's house,

And I will raise up for myself a faithful priest, who shall do according to what is in my heart and in my mind; and I will build him a sure house; and he shall walk before mine anointed continually.

I said, The Philistines will come down now upon me to Gilgal, and I have not made supplication to Jehovah; and I forced myself, and offered up the burnt-offering.

And David said to Jonathan, Behold, to-morrow is new moon, and I should not fail to sit with the king at meat; but let me go, that I may hide myself in the field until the third evening.

And blessed be thy discernment, and blessed be thou, who hast kept me this day from coming with bloodshed, and from avenging myself with mine own hand.
