וּבְפָרִשְׂכֶ֣ם כַּפֵּיכֶ֗ם אַעְלִ֤ים עֵינַי֙ מִכֶּ֔ם גַּ֛ם כִּֽי־תַרְבּ֥וּ תְפִלָּ֖ה אֵינֶ֣נִּי שֹׁמֵ֑עַ יְדֵיכֶ֖ם דָּמִ֥ים מָלֵֽאוּ׃
Quando estenderdes as vossas mãos, esconderei de vós os meus olhos; e ainda que multipliqueis as vossas orações, não as ouvirei; porque as vossas mãos estão cheias de sangue.
Rashi on Isaiah
And when you spread out your hands, I will hide My eyes from you because your hands are full of blood.
Ibn Ezra on Isaiah
ובפרשכם And when ye spread forth. The Hirik under ר is instead of Segol.37The infinitive Piel is פָּרֵש ; when כֶם is added the syllable רֵש loses the accent, and the long vowel Zere must therefore be shortened; this is usually done by changing Zere into Segol; to change it into Hirek, as in וּבְפֽרִשְׁכֶם, is exceptional.
