כִּ֣י נָטַ֗שְׁתָּה עַמְּךָ֙ בֵּ֣ית יַעֲקֹ֔ב כִּ֤י מָלְאוּ֙ מִקֶּ֔דֶם וְעֹֽנְנִ֖ים כַּפְּלִשְׁתִּ֑ים וּבְיַלְדֵ֥י נָכְרִ֖ים יַשְׂפִּֽיקוּ׃
For Thou hast forsaken Thy people the house of Jacob; For they are replenished from the east, And with soothsayers like the Philistines, And they please themselves in the brood of aliens.
Read halakhic rulings (Jewish law) on Isaiah 2:6: and classical halakhic sources.
