'Myself' in the Bible

He said, “I heard the sound of You [walking] in the garden, and I was afraid because I was naked; so I hid myself.”

Abraham answered, “Now behold, I who am but dust [in origin] and ashes have decided to speak to the Lord.

And he said, “Now behold, I have decided to speak to the Lord [again]. Suppose [only] twenty [righteous people] are found there?” And the Lord said, “I will not destroy it for the sake of the twenty.”

and said, “By Myself (on the basis of Who I Am) I have sworn [an oath], declares the Lord, that since you have done this thing and have not withheld [from Me] your son, your only son [of promise],

‘My father made me swear [an oath], saying, “Hear me, I am about to die; bury me in my tomb which I prepared for myself in the land of Canaan.” So now let me go up [to Canaan], please, and bury my father; then I will return.’”
