פירוש על ישעיהו 51:10

Which hath dried the sea. This refers to the division of the Red Sea. מי תהום רבה The waters of the great deep. Repeat הטחרבת which hath dried before these words.

השמה That hath made. It is in form similar to השבה that hath returned (Ruth 2:6). The second part of the verse is a mere repetition of the idea contained in the first.
