תּלמוד אויף בראשית 16:8

Rabbah said to Rava bar Mari. Where is this thing that the sages [mss. read "people"] say derived from: “If your fellow calls you an ass, prepare a saddle for your back”? [Rabbah bar Mari] said to [Rava]: As it is written: “And he said: Hagar, maidservant of Sarai where are you coming from, and where are you going? And she said: I am fleeing from Sarai my mistress” (Genesis 16:8).
