הִ֭תְרַפִּיתָ בְּי֥וֹם צָרָ֗ה צַ֣ר כֹּחֶֽכָה׃
Jika engkau mengendur pada hari kesesakan, kekuatanmu pun akan menjadi sempit.
Rashi
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
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.”
