תְּפַלְּטֵנִי֮ מֵרִ֪יבֵ֫י עָ֥ם תְּ֭שִׂימֵנִי לְרֹ֣אשׁ גּוֹיִ֑ם עַ֖ם לֹא־יָדַ֣עְתִּי יַֽעַבְדֽוּנִי׃
Thou hast delivered me from the contentions of the people; Thou hast made me the head of the nations; a people whom I have not known serve me.
Read halakhic rulings (Jewish law) on Psalms 18:44: and classical halakhic sources.
