כִּ֤י רֶ֨גַע ׀ בְּאַפּוֹ֮ חַיִּ֪ים בִּרְצ֫וֹנ֥וֹ בָּ֭עֶרֶב יָלִ֥ין בֶּ֗כִי וְלַבֹּ֥קֶר רִנָּֽה׃
For His anger is but for a moment, His favour is for a life-time; weeping may tarry for the night, but joy cometh in the morning.
Read kabbalistic (mystical) interpretation of Psalms 30:6: and classical mystical sources.
