הָעֲנִיִּ֨ים וְהָאֶבְיוֹנִ֜ים מְבַקְשִׁ֥ים מַ֙יִם֙ וָאַ֔יִן לְשׁוֹנָ֖ם בַּצָּמָ֣א נָשָׁ֑תָּה אֲנִ֤י יְהוָה֙ אֶעֱנֵ֔ם אֱלֹהֵ֥י יִשְׂרָאֵ֖ל לֹ֥א אֶעֶזְבֵֽם׃
The poor and needy seek water and there is none, And their tongue faileth for thirst; I the LORD will answer them, I the God of Israel will not forsake them.
