וְקִרְע֤וּ לְבַבְכֶם֙ וְאַל־בִּגְדֵיכֶ֔ם וְשׁ֖וּבוּ אֶל־יְהוָ֣ה אֱלֹֽהֵיכֶ֑ם כִּֽי־חַנּ֤וּן וְרַחוּם֙ ה֔וּא אֶ֤רֶךְ אַפַּ֙יִם֙ וְרַב־חֶ֔סֶד וְנִחָ֖ם עַל־הָרָעָֽה׃
And rend your heart, and not your garments, And turn unto the LORD your God; For He is gracious and compassionate, long-suffering, and abundant in mercy, And repenteth Him of the evil.
Pirkei Avot
Rabbi Shimon said: Be careful with the reading of Shema and the prayer, And when you pray, do not make your prayer something automatic, but a plea for compassion before God, for it is said: “for he is gracious and compassionate, slow to anger, abounding in kindness, and renouncing punishment” (Joel 2:13); And be not wicked in your own esteem.
