ישימות [יַשִּׁ֤י] [מָ֨וֶת ׀] עָלֵ֗ימוֹ יֵרְד֣וּ שְׁא֣וֹל חַיִּ֑ים כִּֽי־רָע֖וֹת בִּמְגוּרָ֣ם בְּקִרְבָּֽם׃
May He incite death against them, Let them go down alive into the nether-world; For evil is in their dwelling, and within them.
Read halakhic rulings (Jewish law) on Psalms 55:16: and classical halakhic sources.
