Genesis 19:7

And said, I pray you, brethren
Not by family or nation, for the Sodomites were of the race of Ham, in the line of Canaan, and Lot was a descendant of Shem, in the line of Arphaxad; nor by religion, for the one were idolaters, and the other a worshipper of the true God, but by community of nature; and especially he called them so by reason of their having been neighbours considerable time, and on the score of friendship, see ( 1 Kings 9:13 ) ; and with this soft and loving language Lot hoped to win his neighbours, and to persuade them from pursuing their unlawful measures: for which purpose and that alone he used it, saying to them,

do not so wickedly;
as to use ill a man's guests, to abuse strangers, to break the laws and rules of hospitality, and especially to commit that unnatural sin they were bent upon.
