“And (Lot) said: Behold now, my lords, turn aside, please, into your servant’s house…” (Genesis 19:2)
Abraham’s nephew Lot requested his visitors to enter “your servant’s house”. Abraham, however, said to his guests, “if I find favor in your eyes, please don’t just pass by your servant” (Genesis 18:3). He made no mention of his house, for when he would receive visitors, he would not think of himself as master of his house. Abraham would place his home directly at the disposal of his guests, regarding himself as nothing more than their servant. (Mi’maayanot HaTorah)
