כְּהָקִ֥יר בור [בַּ֙יִר֙] מֵימֶ֔יהָ כֵּ֖ן הֵקֵ֣רָה רָעָתָ֑הּ חָמָ֣ס וָ֠שֹׁד יִשָּׁ֨מַע בָּ֧הּ עַל־פָּנַ֛י תָּמִ֖יד חֳלִ֥י וּמַכָּֽה׃
Comme une source laisse jaillir ses eaux, ainsi elle laisse jaillir sa perversité; on n’y entend que violence et oppression, mes yeux n’y voient que souffrances et sévices.
Rashi
The Midrash connects the word פניו in על פניו with פנים anger — he (Jacob) was also in an angry mood that it should be necessary for him to do all this (Genesis Rabbah 76:8).
Ibn Ezra
The Hebrew word for “well” is a feminine noun and denotes flowing water, as in “as a well keeps its water fresh” [Jeremiah 6:7]. A ditch is a cistern or a hole dug for collecting rainwater. Thus, a well is similar to a fountain . There was no need for the verse also to mention streams. The reasons Scripture speaks of a ditch of gathered water is that a ditch may also not have water. However, some say that the verse omits a connective, and that the verse should read “…a ditch, [or] gathered water…” (as in “Reuven [and] Shim‘on” [Exodus 1:2], “the sun [and] moon” [Habakkuk 3:11]).
