בַּיָּמִ֨ים הָהֵ֜מָּה וּבָעֵ֤ת הַהִיא֙ נְאֻם־יְהוָ֔ה יָבֹ֧אוּ בְנֵֽי־יִשְׂרָאֵ֛ל הֵ֥מָּה וּבְנֵֽי־יְהוּדָ֖ה יַחְדָּ֑ו הָל֤וֹךְ וּבָכוֹ֙ יֵלֵ֔כוּ וְאֶת־יְהוָ֥ה אֱלֹהֵיהֶ֖ם יְבַקֵּֽשׁוּ׃
In those days, and in that time, saith the LORD, The children of Israel shall come, They and the children of Judah together; They shall go on their way weeping, And shall seek the LORD their God.
