בראשית יח:כז פירוש: רש״י, ספורנו, רד״ק ורבנו בחיי

הואלתי means I am willing to speak, just as (Exodus 2:21) “And Moses was pleased (ויואל) [to dwell with the man]”.

I have begun. To present my inquiry regarding Divine justice. I am but dust and ashes.

ויען..הואלתי, “I wanted to speak some more to G’d, אנכי עפר ואפר, even though compared to You I am only dust and ashes. I did not mean to protest Your justice, but I merely wish to understand it.
