כִּֽי־עַתָּ֗ה מֵח֣וֹל יַמִּ֣ים יִכְבָּ֑ד עַל־כֵּ֝֗ן דְּבָרַ֥י לָֽעוּ׃
Poiché ora sarebbe più pesante della sabbia dei mari; per questo le mie parole sono confuse.
Rashi
stammer Heb. לעו. They are uncertain, like a person who has no strength to pronounce a word properly. Likewise (Obad. 16), “And they shall drink and stammer (ולעו),” because it is usual for a drunkard to stammer in his speech.
