Liturgy zu Divrej Hajamim I 21:78

"And with an outstretched forearm" - this [refers to] the sword, as it is stated (I Chronicles 21:16); "And his sword was drawn in his hand, leaning over Jerusalem."

(Some are accustomed to say:) In my remembering upon my bed, the wantonness of my heart and its faults, I will get up and go to the House of my God and His footstool. And I will say in raising my eye, in my supplications, to His skies, "Let us fall into the hand of the Lord, for His compassion is great" (II Samuel 24:14).
