וְנָקַ֥ל זֹ֖את בְּעֵינֵ֣י יְהוָ֑ה וְנָתַ֥ן אֶת־מוֹאָ֖ב בְּיֶדְכֶֽם׃
A to zbyt błahem jeszcze dla Wiekuistego; wyda On i Moabitów w moc waszą.
Rashi
This is easy. And furthermore, this miracle is slight and insignificant in the eyes of God, and He will proceed to act wondrously with you and [perform] another miracle, and He will deliver Moav into your hand.
