Genesis 18 Overview
Genesis 18 records the LORD appearing to Abraham as three visitors arrive near Mamre. Abraham provides generous hospitality, and the promise of Sarah’s son within a set time is repeated. Sarah laughs inwardly, and the LORD asks whether anything is too hard for him. The scene then turns toward Sodom: the LORD reveals the coming investigation and judgment, and Abraham intercedes repeatedly for the city on behalf of the righteous.
