הַיֹּצֵ֣ר יַ֣חַד לִבָּ֑ם הַ֝מֵּבִ֗ין אֶל־כָּל־מַעֲשֵׂיהֶֽם׃
저는 일반의 마음을 지으시며 저희 모든 행사를 감찰하시는 자로다
Rashi on Psalms
He Who forms their hearts together All of their hearts together and knows all the thoughts. Our Sages, however, explain that it refers back to “From His dwelling place, the Creator oversees their hearts together,” and they derived from here that all are examined with a single glance (Rosh Hashana 18a).
