וַֽיִּמְצָאָ֞הּ מַלְאַ֧ךְ יְהוָ֛ה עַל־עֵ֥ין הַמַּ֖יִם בַּמִּדְבָּ֑ר עַל־הָעַ֖יִן בְּדֶ֥רֶךְ שֽׁוּר׃
And the angel of the LORD found her by a fountain of water in the wilderness, by the fountain in the way to Shur.
Targum Jonathan on Genesis
And the Angel of the Lord found her at the fountain of waters in the desert; at the fountain of waters which is in the way to Chagra.
