וְלֹֽא־מֵעֵ֥בֶר לַיָּ֖ם הִ֑וא לֵאמֹ֗ר מִ֣י יַעֲבָר־לָ֜נוּ אֶל־עֵ֤בֶר הַיָּם֙ וְיִקָּחֶ֣הָ לָּ֔נוּ וְיַשְׁמִעֵ֥נוּ אֹתָ֖הּ וְנַעֲשֶֽׂנָּה׃
Ni está de la otra parte de la mar, para que digas: ¿Quién pasará por nosotros la mar, para que nos lo traiga y nos lo represente, á fin de que lo cumplamos?
Mesilat Yesharim
It is what takes a person away from the service of G-d, for so many prayers are lost and so many mitzvot are neglected due to excessive preoccupation and much laboring after profit. How much more so regarding Torah study as our sages said (Eruvin 55a): "'it is not over the sea' (Devarim 30:13) - with those who travel over the seas for business".
Orchot Tzadikim
It is written in the Torah, "It is not in heaven" (Deut. 30:12) and the meaning of this is : it is not to be found among those that are arrogant and consider themselves as high as heaven. "Neither is it beyond the sea" (Deut. 30:13), which means that it is not to be found among those who are constantly travelling on sea voyages (Erubin 55a). Therefore, our Sages, of blessed memory, said, "Nor can one who is engaged overmuch in business grow wise" (Aboth 2:6). And they said, "Engage less in business, but occupy yourself with the Torah" (Aboth 4:12).
