שָׁ֤ם ׀ פָּֽחֲדוּ־פַחַד֮ לֹא־הָ֪יָה֫ פָ֥חַד כִּֽי־אֱלֹהִ֗ים פִּ֭זַּר עַצְמ֣וֹת חֹנָ֑ךְ הֱ֝בִשֹׁ֗תָה כִּֽי־אֱלֹהִ֥ים מְאָסָֽם׃
There are they in great fear, where no fear was; For God hath scattered the bones of him that encampeth against thee; Thou hast put them to shame, because God hath rejected them.
Read halakhic rulings (Jewish law) on Psalms 53:6: and classical halakhic sources.
