הִ֭תְרַפִּיתָ בְּי֥וֹם צָרָ֗ה צַ֣ר כֹּחֶֽכָה׃
네가 만일 환난날에 낙담하면 네 힘의 미약함을 보임이니라
Rashi on Proverbs
on a day of trouble your strength will be weak indeed The ministering angels will not maintain your strength. This is the midrash of the Sages (Midrash Mishle ad loc., Berachoth 63a). But according to its simple meaning, you have become lax on the day of your friend’s trouble, and stand from afar.
Rashi on Proverbs
your strength will be weak indeed on the day of your punishment, as it is written (Esther 4:14): “For if you remain silent, etc.”
