Charles Ellicott Commentary Genesis 19:9

"And they said, Stand back. And they said, This one fellow came in to sojourn, and he will needs be a judge: now will we deal worse with thee, than with them. And they pressed sore upon the man, even Lot, and drew near to break the door." — Genesis 19:9 (ASV)

This one fellow came in to sojourn. — Hebrew: the one came to sojourn, as if an extraordinary concession had been made in Lot’s favour in allowing him to dwell within their walls. In ancient times the rights of citizenship were most jealously guarded, and the position of a sojourner made very bitter.

He will needs be a judge. — Hebrew: is ever acting as a judge. This suggests that Lot had previously reproved the men of Sodom, and agrees with 2 Peter 2:8.
