וְשַׂמְתִּ֣י פְדֻ֔ת בֵּ֥ין עַמִּ֖י וּבֵ֣ין עַמֶּ֑ךָ לְמָחָ֥ר יִהְיֶ֖ה הָאֹ֥ת הַזֶּֽה׃
I uczynię przedział między ludem Moim, a ludem twoim. Jutro stanie się znak ten!"
Rashi
ושמתי פדות AND I WILL MAKE A DELIVERANCE which shall serve as a division BETWEEN MY PEOPLE AND THY PEOPLE.
Rashbam
ושמתי פדות, a word describing “separation.” Words such as ישועה, הצלה, חלצה, פורקן are all expressions denoting different separations, isolation of one thing from another.
Sforno
ושמתי פדות בין עמי ובין עמך, so that even the few members of my people who might be in an area infested by the arov would not be molested by these beasts. The same beasts would harm your people on the same spot.
