Exodus 2:15

וישמע פרעה AND PHARAOH HEARD IT — they (Dathan and Abiram) slandered (denounced) him (Exodus Rabbah 1:31). ויבקש להרג את משה AND HE SOUGHT TO SLAY MOSES — He handed him over to the executioner to slay him, but the sword proved powerless against him. It is to this that Moses referred when he said, (18:4) “And He delivered me from Pharaoh’s sword” (see Mechilta יתרו and Exodus Rabbah 1:31). [וישב בארץ מדין AND HE ABODE IN THE LAND OF MIDIAN — the word וישב means he stayed there, as (Genesis 37:1) “And Jacob abode (וישב)‎”.] וישב על הבאר — Here the word וישב has the meaning of sitting down. He learnt to sit at the well from Jacob whose marriage had been brought about by means of a well (Exodus Rabbah 1:32).

וַיִּשְׁמַ֤ע פַּרְעֹה֙ אֶת־הַדָּבָ֣ר הַזֶּ֔ה וַיְבַקֵּ֖שׁ לַהֲרֹ֣ג אֶת־מֹשֶׁ֑ה וַיִּבְרַ֤ח מֹשֶׁה֙ מִפְּנֵ֣י פַרְעֹ֔ה וַיֵּ֥שֶׁב בְּאֶֽרֶץ־מִדְיָ֖ן וַיֵּ֥שֶׁב עַֽל־הַבְּאֵֽר׃

Now when Par῾o heard this thing, he sought to slay Moshe. But Moshe fled from before Par῾o and dwelt in the land of Midyan: and he sat down by a well.
