Rashi on Genesis 21:22/רש"י על בראשית כ״א:כ״ב

1אלהים עמך GOD IS WITH THEE — They said this because they saw that he had left the locality of Sodom safely, that he had fought against the kings and that they had fallen into his hand, and that his wife had been remembered in his old age (Genesis Rabbah 54:2).
