וְהָיָ֨ה לְא֥וֹת וּלְעֵ֛ד לַֽיהוָ֥ה צְבָא֖וֹת בְּאֶ֣רֶץ מִצְרָ֑יִם כִּֽי־יִצְעֲק֤וּ אֶל־יְהוָה֙ מִפְּנֵ֣י לֹֽחֲצִ֔ים וְיִשְׁלַ֥ח לָהֶ֛ם מוֹשִׁ֥יעַ וָרָ֖ב וְהִצִּילָֽם׃
Hal itu akan menjadi tanda dan kesaksian bagi Yang Mahakekal semesta alam di negeri Mesir; sebab apabila mereka berseru kepada Yang Mahakekal karena para penindas, Ia akan mengutus kepada mereka seorang penyelamat dan pembesar, dan ia akan melepaskan mereka.
Rashi
And it shall be The altar shall be for a sign and for a witness between them and the Omnipresent.
Ibn Ezra
They shall cry unto the Lord because of the oppressors, etc. Whosoever will be in trouble will come thither to bring his offering.
