אֳנִיּ֣וֹת תַּרְשִׁ֔ישׁ שָׁרוֹתַ֖יִךְ מַעֲרָבֵ֑ךְ וַתִּמָּלְאִ֧י וַֽתִּכְבְּדִ֛י מְאֹ֖ד בְּלֵ֥ב־יַמִּֽים׃
די שיפֿן פֿון תַּרְשִישהאָבן דיר דײַן האַנדל געבראַכט. און האָסט זיך אָנגעפֿילט, און ביסט זײער שװער געװען, אין האַרץ פֿון די ימען.
Rashi
Ships...your plains [Heb. שָּׁרוֹתַיִךּ.] They were to you as a plain and a flat terrain. Just as the flat terrain is a paved road, upon which to bring merchandise to a city situated on dry land, the ships of Tarshish were for you instead of them (sic) as a highway for bringing your merchandise into your midst.
Rashi
your plains [Heb. שָּׁרוֹתַיִךּ,] an expression for Sharon and flat terrain. A similar instance is (Jer. 5:10): “Ascend upon its rows בְּשָׁרוֹתֶיהָ.”
Rashi
and you were filled and you became very heavy They brought a great burden into your midst and made your load too heavy.
