וּפֵרַ֤שׂ יָדָיו֙ בְּקִרְבּ֔וֹ כַּאֲשֶׁ֛ר יְפָרֵ֥שׂ הַשֹּׂחֶ֖ה לִשְׂח֑וֹת וְהִשְׁפִּיל֙ גַּֽאֲוָת֔וֹ עִ֖ם אָרְבּ֥וֹת יָדָֽיו׃
E estenderá as suas mãos no meio disso, assim como as estende o nadador para nadar; mas o SENHOR abaterá a sua altivez juntamente com a perícia das suas mãos.

Ibn Ezra on Isaiah
And he shall spread forth. The Lord shall spread forth. In the midst of them. In the midst of Moab.
