לִקְרֹ֤א שְׁנַת־רָצוֹן֙ לַֽיהוָ֔ה וְי֥וֹם נָקָ֖ם לֵאלֹהֵ֑ינוּ לְנַחֵ֖ם כָּל־אֲבֵלִֽים׃
To proclaim the year of the LORD’S good pleasure, And the day of vengeance of our God; To comfort all that mourn;

a year of acceptance A year of appeasement and good will.

All that mourn for Zion, as is said in the next verse.
