אֲשֶׁ֨ר הַמִּתְבָּרֵ֜ךְ בָּאָ֗רֶץ יִתְבָּרֵךְ֙ בֵּאלֹהֵ֣י אָמֵ֔ן וְהַנִּשְׁבָּ֣ע בָּאָ֔רֶץ יִשָּׁבַ֖ע בֵּאלֹהֵ֣י אָמֵ֑ן כִּ֣י נִשְׁכְּח֗וּ הַצָּרוֹת֙ הָרִ֣אשֹׁנ֔וֹת וְכִ֥י נִסְתְּר֖וּ מֵעֵינָֽי׃
So that he who blesseth himself in the earth Shall bless himself by the God of truth; And he that sweareth in the earth Shall swear by the God of truth; Because the former troubles are forgotten, And because they are hid from Mine eyes.
