창세기 16:7 해설: Chizkuni, Sforno, Kitzur Ba'al HaTurim & Radak

במדבר, על העין בדרך שור, “in the desert, by a well, on the way to Shur.” This location is one that the Israelites traversed as mentioned in Exodus 15,22.

וימצאה מלאך ה, the angel found her in a state of readiness to receive a Divine vision. As a result, he appeared o her. [after all it is not likely that an angel roamed the earth looking for Hagar. Ed.]

"Upon the well of water" - In the Tanakh, it is said: "And he said, 'Hagar, Sarah's maid, from where did you come, and where are you going?' And she said, 'I am fleeing from the presence of my mistress Sarah.'" (Gen. 16:8) Here and there, behold, I am standing over the well of water. It is good to pray over the water, as it is written, "the voice of splendor is in the waters" (Psalm 29:3), meaning that there the righteous give charity in the name of God. Similarly, prayer is compared to water, as it is written, "Pour out your heart like water before the presence of God" (Lamentations 2:19).
