Genesis 18:27

And Abraham answered and said
In a very humble and modest manner, encouraged by the answer given him: behold now, I have taken upon me to speak unto the Lord;
suggesting that it was bold and daring in him, and was what he was unfit for and unworthy of; or, "I have begun to speak" ^F5; and since he had, he intimates, it would be a favour, and what he was undeserving of, might he be permitted to proceed; or, "I am desirous to speak" ^F6; it is a pleasure to me, as well as an honour done me, to be permitted to speak unto the Lord, though I deserve it not, which [am but] dust and ashes;
whose original was out of the dust, and to which he would return, and was now a frail, feeble, mortal creature, mean and despicable, unworthy to speak to God; the disproportion between the speaker and the person spoken to was infinite; wherefore the most profound humility and self-abasement are necessary in a creature's approach to the divine Being.
