Exodus 15:16

תפל עליהם אימתה THERE SHALL FALL UPON THEM DREAD — upon those of them who are far away (Mekhilta), ופחד AND HORROR — shall fall upon those of them who are near by; and all this really happened just as the matter is stated, (Joshua 2:10) “For we have heard how the Lord dried up [the waters of the Red Sea]” (Mekhilta). עד יעבר ... עד יעבר TILL THY PEOPLE PASS … TILL THE PEOPLE PASS — The repetition must be explained as the Targum takes it (until they pass over the Arnon, until they pass over the Jordan). קנית denotes [THE PEOPLE] WHICH THOU HOLDEST DEAR above all peoples — like an article purchased (קנוי) at a high price and which is therefore held in affection by the man who bought it.

תִּפֹּ֨ל עֲלֵיהֶ֤ם אֵימָ֙תָה֙ וָפַ֔חַד        בִּגְדֹ֥ל זְרוֹעֲךָ֖ יִדְּמ֣וּ כָּאָ֑בֶן        עַד־יַעֲבֹ֤ר עַמְּךָ֙ יְהֹוָ֔ה        עַֽד־יַעֲבֹ֖ר עַם־ז֥וּ קָנִֽיתָ׃        

Fear and dread shall fall upon them; by the greatness of thy arm they shall be as still as a stone; till thy people pass over, O Lord, till the people pass over, whom thou hast acquired.
