נוֹתֵ֣ן לָ֭רָשׁ אֵ֣ין מַחְס֑וֹר וּמַעְלִ֥ים עֵ֝ינָ֗יו רַב־מְאֵרֽוֹת׃
Donner au pauvre, ce n’est pas se priver: qui en détourne les regards est chargé de malédictions.
Rashi on Proverbs
will suffer no want (to give him much charity.) And so it is with the teacher who does not withhold Torah from his pupil.
