וְהָיָ֕ה בַּאֲכָלְכֶ֖ם מִלֶּ֣חֶם הָאָ֑רֶץ תָּרִ֥ימוּ תְרוּמָ֖ה לַיהוָֽה׃
ay mangyayari na kapag kayo ay kumain ng tinapay ng lupain, kayo ay magbubukod ng isang bahagi bilang handog na ibinubukod para sa Walang-Hanggan.
Zohar
In fact, Joshua and the elders who survived him were also forbidden to attack Moab because they were all members of the Beth Din of Moses, and what was forbidden to Moses was forbidden to them, and also because the precious pearls had not yet issued from them. For Ruth was in the days of the Judges. She was the daughter of Eglon, King of Moab, and when Eglon was killed by Ehud they appointed another king, and his daughter was left in charge of a guardian. When Elimelech came to the field of Moab she married his son.
