. הַקָּדוֹשׁ בָּרוּךְ הוּא בִּיקֵּר חוֹלִים, דִּכְתִיב: ״וַיֵּרָא אֵלָיו ה׳ בְּאֵלֹנֵי מַמְרֵא״ — אַף אַתָּה בַּקֵּר חוֹלִים.

[Just as] The Holy One, Blessed be He, visits the sick, as it is written “And the Lord appeared unto him by the terebinths of Mamre”, so too, should you visit the sick. - Sotah 14A
