מדרש על בראשית 19:21

(Bamidbar 6:26) "The L-rd lift His countenance unto you": when you stand in prayer), as it is written (in respect to the prayers of Abraham, Bereshit 19:21): "Behold, I have lifted your countenance." Now does this not follow a fortiori, viz.: If I have lifted the countenance for Lot for the sake of Abraham, My beloved, shall I not do so for you, and for the sake of your fathers!
