וַאֲנִ֣י יָדַ֔עְתִּי כִּ֠י לֹֽא־יִתֵּ֥ן אֶתְכֶ֛ם מֶ֥לֶךְ מִצְרַ֖יִם לַהֲלֹ֑ךְ וְלֹ֖א בְּיָ֥ד חֲזָקָֽה׃
Targum Jonathan on Exodus
But it is manifest before Me that the king of Mizraim will not let you go, (no,) not from fear of Him who is Mighty, until that by My Word he shall have been punished with evil plagues.
